  • receiving "command not found" error messages after fresh reinstall of Lubuntu 14.04

    - by user236378
    Lubuntu 14.04 was working really great. . .until I messed up and had to do a complete fresh reinstall. Now I receive error messages when I input commands into the Terminal, even after immediately completing the fresh install. For example I type: sudo leafpad ?/etc/default/ or sudo leafpad ?/etc/default/grub I get: sudo: leafpad: command not found I type: sudo update-initramfs ?-u or sudo update-grub I get: sudo: update-initramfs: command not found or sudo: update-grub: command not found If I use the command mkdir I get: mkdir: command not found I also get this same exact error message, command not found, with sudo apt-get and wget In other words I can't do anything that I was able to do when inputting commands into the terminal. So I cannot add any repositories or update anything at all. I am not really sure what is causing the problem(s). It appeared to me that Lubuntu installed and booted up OK. However just as soon as I enter anything into the Terminal I immediately get the above error messages. I have tried to do the reinstall three times, same error messages. If anyone can suggest any fixes I would really appreciate it very much. Thank you!

  • Kubuntu 11.10: How to remove "Search and launch"

    - by user38489
    Is it possible to remove the "Search and launch" whateveritis from my "desktop"? I've actually tried both Desktop and Netbook modes, but it stays there in both of them. I'm not afraid of editing files in the ~/.kde dir, but I would be really disappointed if this is the only way to do it. [more details/rants] I was able to wipe out several things but I've ended up with a black window that's movable (Alt-click) but not removable. Beside being surprised by the performances, I find Kubuntu extremely unfriendly, and I can't find the logic behind the items of the interface. I've tried to search for documentation, but what I've found is not updated and doesn't include the Netbook interface.

  • Is chroot the right choice for my use case?

    - by Anthony
    Backstory: I am working on setting up a MineCraft server and want to allow admins to have ssh access to the MineCraft server console and appropriate mc server files, but not the whole system. The console provided by the minecraft server is only available to the user that launched the process. In addition, the admins will need terminal access to some basic cli tools such as wget, cp, mv, rm, and a text editor. Plan: I have already setup the ssh aspect of things, requiring pre-shared keys and whatnot. Setup a jailed environment in which all user activity will be contained. Setup user accounts. - The first user account will be the minecraft user. The minecraft user will start the MC server in a multiuser screen session and allow the other admins to attach to it. - Subsequent users should have their own /home directory for normal usage. Setup acl for the appropriate files to allow each user to edit the mc server files. No one will be doing system updates, nor will anyone be installing any programs, so I'll be the only user with sudo. The Issues: I don't want the ssh users to have access to the whole system. Users will still need to use wget or curl to update the mc server files. Is chroot the right tool for this use case, or is there something more appropriate for the job? I have no experience setting up a chroot environment and have found several tools to aid in this process. Jailkit seems to be the most robust, but it's not in the standard repos.

  • blurry images with mogrify & convert

    - by user140393
    Does anyone know why this image is so blurry? I did a convert from pdf to png and it turned out like that. Before deleting imagemagick and it's entire toolset from software-center most of my image programs were displaying like this image. Now for the most part it's just blurry, though a couple still display like that such as gimp. I am running in xfce maybe it's to do with the distribution enviornment. Main issue is the absurd blurriness. I reinstalled all additional packages that were available for imagemagick in the software-center I use convert *.pdf *.png & mogrify -format png *.pdf to convert Now on the other hand if I converted the file to djvu and converted that to a tif. The images have no problem converting. More so it does not generate an oversized tif file of around 25mb compared to 3mb with djvu which is super clear & no blurriness.

  • Getting "System program problem detected" pops up regularly after dist-upgrade

    - by grrrbytes
    This started to happen immediately after I had rebooted the first time after doing a system upgrade to 12.04 from 11.10. It first starts with a dialogue that says "System program problem detected". Then when I try to hit 'report problem' not much happens. I am led through a dialogue that always ends up the problem cannot be solved. I am running a MacBook1,1 I am aware this is not a lot of information, however I'm not sure which information I need to publish and how should I obtain it to debug this problem. Here's a screenshot!

  • how to have 'find' not return the current directory

    - by Pinpin
    I'm currently trying to find (and copy) all files and folder structure matching a specific pattern, in a specified directory and I'm so nearly there! Specifically, I want to recursively copy all folders not begining with a '_' character from a specified path. find /source/path/with/directories -maxdepth 1 -type d ! -name _\* -exec cp -R {} /destination/path \; In the /source/path/with/directories/ path are machine-specific directories beginning with '_' and others, and I'm only interested in copying the others. For a reason beyond me, the find command returns the /source/path/with/directories/ directory, and therefore copies its content, directories begining with '_' included. Anyone have a hint as to why that is? Thanks, Pascal

  • Lenovo z470 getting hot, after 12.04 install

    - by Rodrigo
    When I was using Windows 7 my notebook temperature was very good, it stayed very cool. After I installed 12.04, my notebook base is hot all the time, I cannot even put my hands on it for a long time. My notebook has a 2nd generation Intel i5 processor. I installed Jupiter and it shows 72 Degrees Celsius constantly. Anyone got a fix for this? I don't want to go back to windows but if I do not find any solution I will have to do it. I'd be very grateful for any help.

  • How can I find out what site a popup ad came from?

    - by ændrük
    This is the situation: I've been browsing the web for an hour in pursuit of some bit of technical information and have visited several dozen websites that I don't even remember anymore. I've finally found what I need so I start closing the web browser, only to discover that — aaargh! — there's a popup ad hiding underneath! My blood boils. What insidious website is responsible for this circumvention of my browser's popup blocker? I want to make it pay for its crime. I'll write angry emails. Leave bad reviews. Even block it from my Google search results — yes, that'll show it! But I've reached an impediment. The offending site has already been closed. Is it too late to deduce the advertisement's origin? Or can I somehow un-pop the popup? Here's a test page. With only the popup left on your screen, can you deduce that it was caused by visiting PasteHTML?

  • Trying to update Asus BIOS: FreeDOS crashes

    - by ZekeDroid
    My UX31 zenbook is experiencing some weird shutdown behavior when the battery drops below 50% and the internet seems to agree that updating the BIOS is a good step forward since there were issue with the kernel before. I downloaded both the correct BIOS file and the windows 7 utility tool and now need to boot FreeDOS to run, however, I've tried every method out there and they all fail (or so I think): Using unetbootin's FreeDOS 1.0 image I get to an error saying it couldn't run drivers then I get to a command line on disk A:. I assumed a dead end. Using unetbootin but with the FreeDOS 1.1 version image downloaded directly: get an error of "bad or missing command interpreter". I looked online and the solutions didn't work either. So, is there an alternative to FreeDOS or to installing a BIOS that I could use?

  • Blocking popups and ads

    - by user74364
    I'm having a fight with ads, popups and tracking cookies. But i'm having some issues. Software used: Chromium 18.0.1025.168 Extensions used: Adblock Plus (Beta)1.2 AdBlock+ Element Hiding Helper1.1.9.18 Better Pop Up Blocker2.1.6 Ghostery3.0.0 With this configuration, i'm always getting this error: Warning: This extension failed to modify a network request because the modification conflicted with another extension. I know if i disable "better popup", this goes away. It's perfectly normal, due to those extensions trying to block the same things. Problem is, i can't live without all of them! Can anyone advise me about some good configuration? Can't live without adblock plus, because i hate ads. Betterpopup blocker is essential too (believe me, chrome doesn't block a lot of popups, and i have a website or 2 that can proove that.) And ghostery is a must... i can't bare the idea of being tracked all the time by some companies. So i'm kinda lost here! everything is needed, but they conflict with each other. i mean, it has to exist a perfect combination out there, i know i'm not the only one hating the privacy issues nowadays! really thankful for any tips guys

  • How to let the browser prefer IPv6 over IPv4?

    - by Grumbel
    I installed miredo and have IPv6 up and running it seems. I can ping6 hosts and download webpages with wget or my webbrowser when I specify IPv6 addresses, however whenever I specify a hostname that is offered over both IPv4 and IPv6 the browser picks the IPv4 address for the connection. How can I change that and let the browser use IPv6 instead of IPv4 if available? Googling around I found a hint that browsers will prefer IPv4 over IPv6 for 6to4/teredo tunnels, but so far I haven't found an explanation why or how to change that.

  • users disappear from options menu when given uids under 1000

    - by Seamus
    I wanted to stop particular user names appearing in the list of names at the log in screen. I remembered reading that this could be achieved by changing the user id of the account to something less than 1000 (I think I made it 990). So I did this. That worked fine, but now when I wanted to change it back, the name is not appearing in the list of user accounts in the users and groups menu under administration. How do I modify the phantom account?

  • How to fix "error: unknown file system" on all available partitions

    - by Jonathan
    I've had a running problem with removing Linux from my Windows 7 laptop. Initially, it was installed as a dual-boot, and worked well. To remove, I deleted the partitions on my laptop. This removed grub, and I was left with needing to enter: set root=... set prefix=... insmod normal normal each restart. I didn't restore the Windows boot-loader and have since re-partitioned my drive. Now, upon reaching the command prompt screen, an ls query showshd0, with three partitions, but none of them have a recognizable boot-loader as each returns with error: unknown file system. Booting from a Windows 7 rescue disk doesn't seem to work, as it sends me to the same command prompt terminal. All I'm looking to do is restore the boot-loader, either grub or Windows 7. Any help would be appreciated. Thanks in advance.

  • Discover Why Computer Shut Down

    - by kzh
    I was at school SSHing to my homebox. All of a sudden, my connection was closed. Attempting to reconnect failed. When I returned home, I discovered that my computer was off. Nobody was at my house and I am sure that I did not have a power outage. How can I figure out how or why my computer shut off? Is there some log in /var/log that could point me in the right direction? Should there be a core dump somewhere that I should find? If so, how do I use core dumps?

  • Chromium and Google Chrome downloading

    - by user286166
    Well, I have sincerely enjoyed having Google Chrome on my linux machine, and have never had any problems until recently. I found that Google Chrome will simply not allow redirected downloads to start. I can download from direct links, but not pages that redirect and "Start in 3 seconds..." I immediately assumed it was the webpage itself, so I refreshed many times. I then restarted the browser, and after another failed attempt, my computer. After that point, I suspected my internet provider was to blame. I tried the redirection link in an alternative browser (Midori), and it worked perfectly fine. I decided it must be the version of Chrome that Google put out, so I quickly installed Chromium, and to my dismay, ran across the same problem. I can live with copying and pasting the url into Midori for redirected links, but I'd like the convenience of staying in my main browser. Thank you for any advice in advance. c:

I read several threads on this topic but I did not find such kind of problem. There is something similar about portege r100 concerning lowgraphics mode but the porblem I have seems to be different because graphics session does not start. Can anyone help me ? Thank you Best

  • Don't show gwibber messages in indicator applet

    - by berkes
    Gwibber turns the indicator-applet-icon blue, each time a new tweet appears in my timeline, which is always. It is therefore no longer usefull as a "there is a new message for you" resulting in many missed jabber/gtalk chats, finding emails half an hour late and so on. How can I mute Gwibber in there? Preferably so it only turns the new-message-icon blue on new replies and private messages in Gwibber. But certainly not on any update.

  • Bit copy of encrypted home and other partitions

    - by Mka
    My laptop is overheating so I need to save all my files before I format the hard drive. I learned how to copy dev/sdX using dd command. However, I am not sure what to copy. Picture from GParted here: http://is.muni.cz/www/256590/fig.png should I copy sda5 and sda6 only? Or sda2 and sda1? I do not need to use these data on another disk, I just want to be able to access them - therefore I want to put them on external hard drive. And last question - how I will then mount my encrypted home? Will it work? Thanks a lot!

  • Is it possible to have .bashrc outside home directory?

    - by FSchmidt
    I want to put a .bashrc file in a directory where my application is located, to set up path variables accordingly independent of the location of the directory at the moment. At the same time, I want to be able to run the application right away, without having to source a shell file to set the path every time. Therefore I figured I could use .bashrc which is executed when the non-login terminal is started. If I do put it in the proper .bashrc in the home directory, I would have to give an absolute path which I want to avoid. Is there a way to have something like .bashrc but not in home directory (ie a shell that is executed when terminal is started?)

  • What are the biggest barriers to walking the MOTU/developer path?

    - by maco
    For those who are not MOTU (people who maintain the Universe and Multiverse software repositories) and do not have plans of the "I will apply to MOTU by $date" variety: What keeps you and others like you from trying to become MOTU? What makes you think you couldn't become one? I'm referring to both social and technological barriers. EDIT: I'm only saying MOTU because it's a pretty generic group, but "why aren't you packaging / patching and intending to eventually try for upload rights?" is an even more general version.
