Status changed to 'Confirmed' because the bug affects multiple users.

Thank you for taking the time to report this bug and helping to make Ubuntu better. The relevant dpkg terminal log says:

```
Setting up usrmerge (25ubuntu2) ...
Smartmatch is experimental at /usr/lib/usrmerge/convert-usrmerge line 172.
mv: cannot remove '/lib/live/mount/overlay': Device or resource busy
mv: cannot remove '/lib/live/mount/rootfs/rescue_rootfs.squashfs/bin/bash': Read-only file system
[...]
mv: cannot remove '/lib/live/mount/medium/live/rescue_rootfs.squashfs': Read-only file system

FATAL ERROR:
mv --no-clobber /lib/live /usr/lib/live: rc=1

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.

dpkg: error processing package usrmerge (--configure):
 installed usrmerge package post-installation script subprocess returned error exit status 1
```

Later initramfs-tools fails:

```
Processing triggers for initramfs-tools (0.140ubuntu13.1) ...
update-initramfs: Generating /boot/initrd.img-5.4.0-152-generic
cp: cannot stat '/lib/live/boot': No such file or directory
live-boot: corecp: cannot stat '/lib/live/boot': No such file or directory
E: /usr/share/initramfs-tools/hooks/live failed with return 1.
update-initramfs: failed for /boot/initrd.img-5.4.0-152-generic with 1.
```

This looks like a follow-up failure of the usrmerge failure. Can you try to complete the usrmerge by following the instruction of the error message above? I'll re-assign this bug to usrmerge.
