<div dir="ltr"><div>Hi again Will,</div><div><br></div><div>Thought about this a bit and here is some hopefully useful advice.</div><div>Trisquel is based off Ubuntu, I am familiar with Ubuntu, and have had great success with in-place upgrade and not losing anything.</div><div></div><ul><li>First, take a back-up</li><ul><li>"Clonezilla" is a great tool.</li><li>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</li></ul><li>Check the backup.</li><ul><li>Pretty sure Clonezilla has some way to verify.</li><li>If you used "dd", you should just be able to mount the partitions</li></ul><li>Update the system: "sudo apt update && sudo apt full-upgrade --allow-downgrades && sudo apt autoremove --purge"</li><li>Might want to consider another back-up here</li><li>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)</li><li>If you use any PPAs, these will be disabled in the next step; you can restore them later</li><li>Upgrade: "sudo do-release-upgrade"</li><li>All being well, this will work sweet as a nut</li><li>If, however, it comes down in screaming flames you will be left in one of two situations.</li><ol><li>
(Unlikely):
Unbootable mess, it's destroyed; try to gather any debug/failure info and restore from backup</li><li>Boots, but then has various whinges, the desktop won't start, applications error, etc.</li></ol><ul><ul><li>Probably down to PPAs, restoring them
(see below)
and then updating has always fixed this for me.</li><li>Or you'll just have to pick through the errors as they get reported<br></li></ul></ul><li>Restore any PPAs by popping into "/etc/apt" and editing "sources.list" and any files under "sources.list.d" <br></li><ul><li>You might need to fiddle with version numbers in the files as they may need updated for the new OS<br></li><li>Entries should be commented out and tagged with "disabled on upgrade to"</li></ul><li>Update again:
"sudo apt update && sudo apt full-upgrade --allow-downgrades && sudo apt autoremove --purge"</li><ul><li>Depending on the version of Ubuntu that was the base, "sudo apt autopurge" might now work instead of that last command<br></li></ul><li>Check that everything works and hopefully you are done!<br></li></ul>
<div>Any questions/problems, get back on the list and I am sure someone can help.</div><div><br></div><div>Best of luck!</div><div><br></div><div>J.<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, 22 Feb 2022 at 18:17, Will White via Nottingham <<a href="mailto:nottingham@mailman.lug.org.uk" target="_blank">nottingham@mailman.lug.org.uk</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Hello Nottingham LUG,<br>

I’m currently running Trisquel 8, and trying to install 9 without losing my workflow (or data).<br>

Nice to be here,<br>
