Recently RISC-V cross-compile GHA on jdk17u-dev failed when creating sysroot on Ubuntu 20.04 runner. I have also tried on my local Ubuntu 20.04 machine, and got the following error:
Setting up systemd (254~rc2-3) ...
Created symlink /etc/systemd/system/getty.target.wants/getty@tty1.service -> /lib/systemd/system/getty@.service.

dpkg: error processing package systemd (--install):

But the JDK mainline GHA still looks good, so I tried to bump the cross-compiling runner to 22.04, and the error was gone.
