Oh, actually, looking deeper, I didn't notice you were on 19.10 to begin with. I'm not sure that we were enforcing file checks then. My comment is still relevant though.
If you can confirm that you did indeed verify the hashes of both the ISO and installation media, then perhaps the next step might be to use something like auditd (https://manpages.ubuntu.com/manpages/focal/man8/auditd.8.html) to figure out what process is changing the file and how often. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1910934 Title: lxqt loses natural scrolling To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxqt-config/+bug/1910934/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
