** Description changed:
+ [Impact]
+
+ * Starting with Ubuntu Hirsute, the 'usrmerge' package is pulled into
+ the default installation, doing the merging of /{bin,sbin,lib}/ and
+ /usr/{bin,sbin,lib} on upgrade. If there are left-over generated files
+ it will fail with an error like this:
+
+ Setting up usrmerge (24ubuntu3) ...
+
+ FATAL ERROR:
+ Both /lib/udev/hwdb.bin and /usr/lib/udev/hwdb.bin exist.
+
+
+ The upgrade has completed but there were errors during the upgrade
+ process.
+
+ * We want a fix in Hirsute+ that clears the old location (e.g.
+ /lib/udev/hwdb.bin) if the file has already been re-generated at the new
+ location (e.g. /usr/lib/udev/hwdb.bin).
+
+
+ [Test Plan]
+
+ Prepare a recent, but non-usrmerge'd system (e.g. launch Bionic and upgrade
to Focal then Hirsute):
+ $ lxc launch ubuntu:bionic usrmerge
+ # do-release-upgrade
+ [...]
+ # reboot
+ # ls -la / # to make sure that /lib is not (yet) a link to /usr/lib
+
+ Simulate duplicated generated files & upgrade:
+ # mkdir -p /usr/lib/udev && cp /lib/udev/hwdb.bin /usr/lib/udev/
+ # vim /etc/update-manager/release-upgrades # change to "Prompt=normal"
+ # do-release-upgrade
+ [...]
+ => Upgrade fails, press "C" to cancel bug report
+ => "The upgrade has completed but there were errors during the upgrade
process."
+
+ Verify that the script still fails:
+ # /usr/lib/usrmerge/convert-usrmerge
+ FATAL ERROR:
+ Both /lib/udev/hwdb.bin and /usr/lib/udev/hwdb.bin exist.
+
+ Install relevant usrmerge package:
+ # wget
https://launchpad.net/ubuntu/+archive/primary/+files/usrmerge_VER_all.deb
+ # dpkg -i usrmerge_VER_all.deb
+ => The system has been successfully converted.
+ # /usr/lib/usrmerge/convert-usrmerge
+ => The system has been successfully converted.
+ # echo $?
+ 0
+
+ [Where problems could occur]
+
+ * The upload modifies the convert-usrmerge script, adding special handling
for certain, generated files.
+ * If something goes wrong, it could delete the wrong state of udev's hwdb
which would be re-generated by systemd-hwdb-update.service
+ * It could also interrupt the upgrade processes on installation of the
usrmerge package, asking the user for manual action (e.g. solving some file
conflict and re-running /usr/lib/usrmerge/convert-usrmerge)
+
+ [Other Info]
+
+ * The patch was sent to Debian: https://bugs.debian.org/997866

I got the following error after upgrading from 20.10 to 21.04:
-

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
