Revision of Migrate from Ubuntu to Trisquel without reinstalling from Sat, 01/14/2017 - 11:01
The revisions let you track differences between multiple versions of a post.
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.
