Installing Lubuntu 14.04.1 forcepae fails
- by Rantanplan
I tried to install Lubuntu 14.04.1 from a CD. First, I chose Try Lubuntu without installing which gave:
ERROR: PAE is disabled on this Pentium M
(PAE can potentially be enabled with kernel parameter "forcepae" ...
Following the description on https://help.ubuntu.com/community/PAE, I used forcepae and tried Try Lubuntu without installing again. That worked fine. dmesg | grep -i pae showed:
[ 0.000000] Kernel command line: file=/cdrom/preseed/lubuntu.seed boot=casper initrd=/casper/initrd.lz quiet splash -- forcepae
[ 0.008118] PAE forced!
On the live-CD session, I tried installing Lubuntu double clicking on the install button on the desktop. Here, the CD starts running but then stops running and nothing happens.
Next, I rebooted and tried installing Lubuntu directly from the boot menu screen using forcepae again. After a while, I receive the following error message:
The installer encountered an unrecoverable error. A desktop session will now be run so that you may investigate the problem or try installing again.
Hitting Enter brings me to the desktop. For what errors should I search? And how?
Finally, I rebooted once more and tried Check disc for defects with forcepae option; no errors have been found.
Now, I am wondering how to find the error or whether it would be better to follow advice c in https://help.ubuntu.com/community/PAE: "Move the hard disk to a computer on which the processor has PAE capability and PAE flag (that is, almost everything else than a Banias). Install the system as usual but don't add restricted drivers. After the install move the disk back."
Thanks for some hints!
Perhaps some of the following can help:
