Ubuntu Support Template
Ubuntu Version:
16.04 LTS
Desktop Environment (if applicable):
server mode
Problem Description:
Because of another problem - I had to resort to backups and the long story short I now have a working 16.04 server system again.
running <sudo do-release-upgrade/>
I get the following:
<Updating repository information
No valid sources.list entry found
While scanning your repository information no entry about xenial could be found
An upgrade might not succeed.
Do you want to continue anyway?/>
I have a backup of the system as it is now, (Ive just restored it from backup).
Is it ok to continue or not - and what should I do to upgrade to 18.04.
Fully understand I need to move to 20.04 and 22.04 afterwards.
Hello rodney-atkins –
Oh Boy - not; Taking this course you are in a for a long hard bumpy road. 4 hops to get to the current LTS release.
And the first two hops via EOLUpgrades - ouch:
https://help.ubuntu.com/community/EOLUpgrades
Though I can attest it can be done (maybe breakage, however, getting over 17.04’s mishaps may be a trial.)
I would give serious consideration to making a clean fresh install of 26.04. 10 years in comutereese is a long time and much has changed.
otherwise
-no luck to this - just hard work-

If you check Support and Help rules you’ll find your release is not a supported release here, being EOL or EOSS (depending on architecture) its now supported only by Canonical (as are 18.04 & 20.04 which release-upgrades will mandate you go though).
The only supported method for this site is to install a supported release and restore your data, as we can’t help you with the harder upgrades you need (16.04 to 18.04, then 18.04 to 20.04) if we’re to remain within site rules, though it’ll be less troublesome with the easier final upgrade to 22.04.
You’ve left it late for an easy release-upgrade path.
You didn’t provide architecture details; but 16.04 is End of Life for some, and End of Standard Support for others, which makes a difference in what is currently available, and where data can be found.
Mirrors are free to drop support once EOL is reached, with some doing it at the earlier EOSS, so you need to account for that too in applying upgrades.
Either way we cannot help with your current off-topic 16.04 needs.
