[Trisquel-users] Free disk space - uninstall old kernels

[mikko . viinamaki]

If you're short of disk space, like many people seem to be, one easy way to  
recover hundreds of megs is to remove old kernels. Looks like the Trisquel  
default kernels are about 150 megs a pop and they never get automatically  
uninstalled as new ones pour in. This is an easy maintenance job.

Open the Synaptic package manager. In the lower left select Status (to look  
at packages depending on their status on your system) and top left select  
installed status. Then write to the Quick filter (top middle) linux-image and  
you will get a list of installed kernels.

The package management will warn you if you try to uninstall the kernel  
you're currently using, don't do it. :) You can see which one you're using by  
opening a terminal and inputting uname -r. When you reboot the newest kernel  
is automatically selected by GRUB by default.

The default kernels will work very likely well, so if you're only using the  
default kernels, you can uninstall all the older ones and just leave the  
latest. If on the other hand you're running and testing custom kernels, then  
you'll probably want to leave the latest default kernel as well, for  
situations the custom kernel might not handle.
