Hello, iirc it was recently proposed to add a suggestion to run dpkg --verify to the trixie upgrade notes to find missing files due to the usr-merge transition. (Cannot find the reference right now).
However I just had file loss (due to libuuid changing its name to t64 and back again) and dpkg --verify (and --audit) is happy: (sid)ametzler@argenau:/tmp$ ldd -r /usr/lib/x86_64-linux-gnu/libSM.so.6 | grep not libuuid.so.1 => not found (sid)ametzler@argenau:/tmp$ dpkg -s libuuid1 Package: libuuid1 Status: install ok installed [...] Version: 2.39.3-7 (sid)ametzler@argenau:/tmp$ dpkg --verify libuuid1 && echo success success (sid)ametzler@argenau:/tmp$ dpkg -L libuuid1 | grep /lib/ /usr/lib/x86_64-linux-gnu (sid)ametzler@argenau:/tmp$ grep /lib/ /var/lib/dpkg/info/libuui d1\:amd64.list /usr/lib/x86_64-linux-gnu (sid)ametzler@argenau:/tmp$ dpkg --contents /var/cache/apt/archives/libuuid1_2.39.3-7_amd64.deb | grep '\.so' -rw-r--r-- root/root 34872 2024-03-01 10:20 ./usr/lib/x86_64-linux-gnu/libuuid.so.1.3.0 lrwxrwxrwx root/root 0 2024-03-01 10:20 ./usr/lib/x86_64-linux-gnu/libuuid.so.1 -> libuuid.so.1.3.0 cu Andreas -- `What a good friend you are to him, Dr. Maturin.
