Migrate from Ubuntu to Trisquel without reinstalling
This script automates all the steps required to migrate from any Ubuntu version to its Trisquel counterpart without reinstalling the system. It will replace the kernel with Linux-libre, remove as many non-free packages as possible and install the default Trisquel package set.
Just copy the script into a file, call it trisquelize.sh and run sudo sh trisquelize.sh.
Notes
- Edit the following variables as needed: $MIRROR $RELEASE and $EDITION
- The sample contents of those variables are intended to migrate from Ubuntu 12.04 Precise to Trisquel 6.0.
- Never attempt to run this script from a Ubuntu edition with no Trisquel counterpart! Ask in the forums if you are in doubt.
- The script attempts to remove a set of known non-free packages available in Ubuntu main and universe repositories; everything else will be preserved.
- If your disk is encrypted make sure you have the plaintext key written down in case something goes wrong.
- Making backups is recommended.
- The script has some long lines; mind them if you modify it.
- If something goes wrong and you need help, paste the contents of /var/log/trisquelize.log in http://trisquel.pastebin.com and ask in the forum posting the link to your log at pastebin.
- We recommend you to join the #trisquel IRC channel at irc.freenode.org during the process, in case you ever need help.
