error: failed to commit transaction (conflicting files)

[sp4d1n0]

Sometimes, due to inconsistencies in the initial rootfs or in the packages selection during the migration process (especially because a WSL2 image do not need the same amount of packages of a live setup), it can happen to see the following error messages during install:

... checking for file conflicts                  [###########################] 100%
error: failed to commit transaction (conflicting files)
runit: /usr/bin/halt exists in filesystem (owned by systemd-sysvcompat)
runit: /usr/bin/poweroff exists in filesystem (owned by systemd-sysvcompat)
runit: /usr/bin/reboot exists in filesystem (owned by systemd-sysvcompat)
runit: /usr/bin/shutdown exists in filesystem (owned by systemd-sysvcompat)
base: /usr/bin/init exists in filesystem (owned by systemd-sysvcompat)
Errors occurred, no packages were upgraded.

It's quite simple to solve!

Just issue the following command should be enough:

rm /usr/bin/{halt,poweroff,reboot,shutdown,init}
