I can confirm this bug. Viewing systemd logs on my system showed the weekly TRIM of /home stopped around the end of October 2019 as reported by Jeffery.
This bug was filed upstream (https://github.com/karelzak/util- linux/issues/824) and will affect users with /home on a separate partition. It was patched with the following one-line commit c64d452b3eb85fe55e238144082247b05cc143ea: -ProtectHome=yes +ProtectHome=read-only ** Bug watch added: github.com/karelzak/util-linux/issues #824 https://github.com/karelzak/util-linux/issues/824 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1858152 Title: fstrim.service no longer trims /home partition To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/1858152/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
