• Moving from xubuntu (24.04) to debian 13, any major gotchas?

    From Chris Green@3:633/10 to All on Saturday, March 07, 2026 11:00:02
    Nearly all my computers run Debian 13 but my wife's Thinkpad is still
    running xubuntu 24.04.

    I think the xubuntu installation on her laptop could do with a
    thorough clean out, it hasn't had a clean installation from scratch
    for many years. Currently the Firefox and Thunderbird snap
    installations seem to be causing problems.

    So I'm thinking that, if I'm going to do a clean install, I may as
    well install Debian 13.

    Her laptop is used nearly wholly for E-Mail and web browsing, nothing
    very techie at all.

    Am I likely to hit any big snags? Obviously I will back things up
    carefully (we have daily incremental backups of /home and /etc
    anyway). Do I need to do much more than make an image of /home and
    then install Debian 13 and then copy /home onto the new install?

    Hello Chris,

    First of all, in case there is a doubt here, I think there is only one
    safe way to go from Ubuntu to Debian: a clean install. Any kind of
    upgrade from Ubuntu from Debian should bring problems.

    Apparently Ubuntu 24.4 linux kernel is version 6.8 while Debian 13
    Trixie is 6.12 so if your wife's laptop works with Ubuntu 24.4 it should
    work with Trixie.

    There would be probably no big problem switching from Ubuntu to Debian.
    But potentially you would have to assert how to handle personal
    application data: Ubuntu apps are often provided as snap packages and I think(1) that you could have to somehow restore the data to the relevant Debian packaged apps. Or you could chose to keep on using snaps on
    Debian, that is possible but it is not the default.

    Take all that with a grain of salt: I have never migrated from Ubuntu to Debian.

    One specific point: /home contains a lot of the users' configuration
    data, some of which may not be compatible with different versions of
    the applications. I would not just drop the old dotfiles into the new
    /home without testing before and after each application for functioning correctly, or if the files are short text files, examining them. In some
    cases, as you say the installation is old, you may want to configure
    from scratch anyway.

    Obviously the data should be safe enough to transfer.

    Ideally, either broken/incompatible data or configuration files should
    not cause an application any difficulty, they should just be reported,
    but some applications don't handle invalid input files gracefully.

    Yes, I guess the best thing to do would be to copy each application's
    data across separately and deal with any issues as one does it.

    Yes, that's why I considered moving to Debian as I had decided a clean
    install was going to be a 'good idea' anyway. :-)

    Trixie is 6.12 so if your wife's laptop works with Ubuntu 24.4 it should work with Trixie.

    Debian, that is possible but it is not the default.

    I want to get away from snap, that's one reason why I migrated all my
    systems to Debian a while ago.

    Thanks.
