[Nottingham] Hello

Hi again Will,

Thought about this a bit and here is some hopefully useful advice.
Trisquel is based off Ubuntu, I am familiar with Ubuntu, and have had great
success with in-place upgrade and not losing anything.

   - First, take a back-up
      - "Clonezilla" is a great tool.
      - You can just use a command like "dd" to dump everything off the
      internal drive onto the backup one, but Clonezilla is going to give you
      more hand-holding and error protection
   - Check the backup.
      - Pretty sure Clonezilla has some way to verify.
      - If you used "dd", you should just be able to mount the partitions
   - Update the system: "sudo apt update && sudo apt full-upgrade
   --allow-downgrades && sudo apt autoremove --purge"
   - Might want to consider another back-up here
   - If you have any really critical files, take a separate copy of those.
   Don't forget any critical settings that might be hiding under the likes of
   "~/.conf" or "~/.mozilla" (finding all the settings files can be a right
   pain)
   - If you use any PPAs, these will be disabled in the next step; you can
   restore them later
   - Upgrade: "sudo do-release-upgrade"
   - All being well, this will work sweet as a nut
   - If, however, it comes down in screaming flames you will be left in one
   of two situations.
      1. (Unlikely): Unbootable mess, it's destroyed; try to gather any
      debug/failure info and restore from backup
      2. Boots, but then has various whinges, the desktop won't start,
      applications error, etc.
   - Probably down to PPAs, restoring them (see below) and then updating
         has always fixed this for me.
         - Or you'll just have to pick through the errors as they get
         reported
         - Restore any PPAs by popping into "/etc/apt" and editing
   "sources.list" and any files under "sources.list.d"
   - You might need to fiddle with version numbers in the files as they may
      need updated for the new OS
      - Entries should be commented out and tagged with "disabled on
      upgrade to"
   - Update again: "sudo apt update && sudo apt full-upgrade
   --allow-downgrades && sudo apt autoremove --purge"
      - Depending on the version of Ubuntu that was the base, "sudo apt
      autopurge" might now work instead of that last command
      - Check that everything works and hopefully you are done!

Any questions/problems, get back on the list and I am sure someone can help.

Best of luck!

J.
