I have updated Ubuntu on notebooks a couple of times from one LTS release to the next. This works well (and is tested) for those packages that are part of the old release, but it does not necessarily work well for packages outside the distribution. apt-mark showmanual should show those manually installed packages on Ubuntu.
(With Arch Linux or Manjaro you can use pacman -Qe instead. In case of Fedora, dnf history userinstalled should produce a list. In CentOS 7, yum history addon-info may be a start.) Obviously you'll have to keep an eye on those extra packages. They will not necessarily be upgraded, and they may even prevent the upgrade from one LTS to the next. When taking this into account, upgrades of LTS versions have worked for me. Hope this helps, Kay ######################################################################## To unsubscribe from the CCP4BB list, click the following link: https://www.jiscmail.ac.uk/cgi-bin/WA-JISC.exe?SUBED1=CCP4BB&A=1 This message was issued to members of www.jiscmail.ac.uk/CCP4BB, a mailing list hosted by www.jiscmail.ac.uk, terms & conditions are available at https://www.jiscmail.ac.uk/policyandsecurity/
