[Bug 2086560] [NEW] lvm2 missing lvresize_fs_helper

[Dan Christian]

Public bug reported:

Ubuntu 24.10 running live from USB
I'm trying to resize some partitions so I can upgrade (because /boot needs more room)

lvresize fails with:
/usr/libexec/lvresize_fs_helper: execvp failed: No such file or directory

This appears to be that lvm2 bug 124 has not been fixed in the shipped
version.  https://github.com/lvmteam/lvm2/issues/124
