I updated and upgraded all packages on my Ubuntu 16.04.7 LTS (Xenial Xerus) in preparation for a release upgrade to 18.04 (Bionic).

I have checked other posts, but my problem is a little different.

I continually get the following message when I run do-release-upgrade:

Checking for a new Ubuntu release
Get:1 Upgrade tool signature [819 B]
Err Upgrade tool
  503  Service Unavailable [IP: 185.125.190.36 80]
Fetched 819 B in 0s (0 B/s)
WARNING:root:file 'bionic.tar.gz' missing
Failed to fetch
Fetching the upgrade failed. There may be a network problem.

I do not know why the system is choosing that IP address and I don't know how to change it.

When I point a web browser at http://185.125.190.36, I see that it does not have the bionic release, Ubuntu 18.04.

I have tried entering various things in /etc/apt/list.sources but nothing works. For example,

deb https://apache.bintray.com/couchdb-deb bionic main

was suggested but the do-release-upgrade ignores it. How can I fix this issue?

  • I don’t think you can upgrade from 16.04 any more as it’s end of life. I think you’ll have to do a fresh install (and would be sensible to go for 22.04LTS to give you maximum life from the os). – Will Mar 23 '23 at 16:12
  • You can upgrade from an EOL release but not in the usual way. A fresh install is a better choice. Also 18.04 is EOL in a few weeks the 5 years is up. Better to do 22.04 or at least 20.04 – David Mar 23 '23 at 16:44
  • Even to do an upgrade and update for 16.04 would not have worked as it is gone. Not sure what it is you did. – David Mar 23 '23 at 16:46
  • Does this answer your question? How to install software or upgrade from an old unsupported release? – mchid Mar 23 '23 at 21:06
  • I think the only difference is that if it tells you that ubuntu-release-upgrader-core does not exist, then you should install update-manager-core instead. – mchid Mar 23 '23 at 21:09

    I've performed an do-release-upgrade from xenial (16.04) to bionic (18.04) within the last week; however my location in the world probably differs (and this can be important unless all upgrades are applied; all upgrades now requiring ESM to be enabled now depending on geolocation due to expired certificates in some areas). Early in the process two tarballs are downloaded (inc., bionic.tar.gz) that direct the upgrade; the site does not come your sources.list files but the upgrade tool. Ensure you've applied all upgrades! – guiverc Mar 23 '23 at 22:15
