Thanks Chris. I checked further on support sites. One suggested redirecting sources (sources.list) from Eoan to "...old-releases.ubuntu...", which I did and allowed me to upgrade to 20.04 (albeit the desktop still says 19.10). I'll see what happens when I try next upgrade. If it's too messy, I'll just do a fresh install. Thanks again for your prompt response.

For help in ensuring you packages are fully upgraded; refer to https://help.ubuntu.com/community/EOLUpgrades I don't have access to an eoan/19.10 system, and online package databases are gone (having been EOL too now long), so I can't look up to see if packages are 3rd party or Ubuntu repositories, so I'll just suggest you 'upgrade via re-install'. You can install using "Manual Partitioning", select your existing partition(s) and as long as you don't format, the installer will - note your packages, - erase system directories (user configs for Lubuntu are stored in $HOME or user directory), - install system, - attempt to add-back additional packages you had install (if available in Ubuntu repositories for the new release) - then ask to reboot. Even if you get a warning that some packages could not be restored (this can occur for numerous reasons, eg. a dropped package as it relied on python2, Qt4 or like deprecated toolkit for example), the warning is rarely of concern. If you have any support questions, I'll also provide the Lubuntu links page https://lubuntu.me/links/ (you may find me there too) -- You received this bug notification because you are subscribed to the bug report. https://bugs.launchpad.net/bugs/1910945 Title: can't upgrade from 19.10 Status in ubuntu-release-upgrader package in Ubuntu: Incomplete Bug description: similar to #934371 but even less detail.
