I have installed Xilinx 14.7 in ubuntu 14.04 LTS machine(i386 - 64bit). But I am unable to run lmgrd (for starting the license server). When I googled this problem, I found that lsb-core package needs to be installed. But the package is having many dependencies, I want to know how to install lsb-core package with all the necessary dependencies. Thanks for the help On running sudo apt-get install lsb-core I got the following output Reading package lists... Done Building dependency tree Reading state information... Done Package lsb-core is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'lsb-core' has no installation candidate So I downloaded lsb-core package from http://packages.ubuntu.com/trusty/misc/lsb-core site and used "sudo dpkg -i ./lsb-core_4.1+Debian11ubuntu6_i386.deb" to install it By doing it, I got the following output Selecting previously unselected package lsb-core.
