<p>Thank you very much Jason. I'd got as far as Clonezilla, so this
will be useful!</p>
<p>Hopefully I'll "see you on the other side".<br>

<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>
<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>
