How to escape this crazy error?
Preconfiguring packages …
Setting up systemd (229-4ubuntu21.1) …
Can’t locate Debian/AdduserCommon.pm in @INC (you may need to install the Debian::AdduserCommon module) (@INC contains: /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.22.1 /usr/local/share/perl/5.22.1 /usr/lib/x86_64-linux-gnu/perl5/5.22 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl/5.22 /usr/share/perl/5.22 /usr/local/lib/site_perl /usr/lib/x86_64-linux-gnu/perl-base .) at /usr/sbin/addgroup line 34.

Use apt-file search AdduserCommon.pm on another Ubuntu VM. APT-File install separately on the maschine. So you can look which packet the file belongs to.
apt-file search AdduserCommon.pm
adduser: /usr/share/perl5/Debian/AdduserCommon.pm
now we reinstall the package adduser
apt-get –reinstall install adduser
Antoher way is copy the whole folder /usr/share/perl5/ from the working vm to the broken vm.
