Hello, During bookworm upgrade, I ran into some usrmerge failures, which led to an hard-to-fix situation
Paramétrage de usrmerge (35) ... FATAL ERROR: Both /lib/x86_64-linux-gnu/libidn.so.11 and /usr/lib/x86_64-linux-gnu/libidn.so.11 exist. You can try correcting the errors reported and running again /usr/lib/usrmerge/convert-usrmerge until it will complete without errors. Do not install or update other Debian packages until the program has been run successfully. E: usrmerge failed. root@corrin:/root # /usr/lib/usrmerge/convert-usrmerge /usr/bin/perl: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.29' not found (required by /usr/bin/perl) /usr/bin/perl: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.28' not found (required by /usr/bin/perl) /usr/bin/perl: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.33' not found (required by /usr/bin/perl) /usr/bin/perl: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by /usr/bin/perl) /usr/bin/perl: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.25' not found (required by /lib/x86_64-linux-gnu/libcrypt.so.1) /usr/bin/perl: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.36' not found (required by /lib/x86_64-linux-gnu/libcrypt.so.1) root@corrin:/root # rm /usr/lib/x86_64-linux-gnu/libidn.so.11 Erreur de segmentation (core dumped) root@corrin:/root # ls -l /usr/lib/x86_64-linux-gnu/libidn.so.11 ls: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.28' not found (required by ls) ls: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.33' not found (required by /lib/x86_64-linux-gnu/libselinux.so.1) ls: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.30' not found (required by /lib/x86_64-linux-gnu/libselinux.so.1) ls: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by /lib/x86_64-linux-gnu/libselinux.so.1) As no system tool was usable in this situation (dpkg crashed too), I powered-off the machine and restored it from backup. I then installed usrmerge on bullseye, fixed the problems, then done the bookworm upgrade without any other problems. As usrmerge is mandatory on bookworm ; and usrmerge failure during upgrade leads to (could lead to ?) big problems ; shouldn't its installation be advised in 4.1 or 4.2 chapters of the upgrade guide ? I know 5.1.14 says merged-/usr is now required ; but it does not warn about failures, and I don't think I'm the only one who don't read the next chapter before starting upgrade ;) Regards, -- Bastien
