I'm upgrading my server from Ubuntu 14.04 to 188.8.131.52 following the guidelines here: https://www.virtualmin.com/documentation/system/os/ubuntu-trusty-to-xenial However, my PC (not server) was shutdown and when I SSH to my server again, it already show the Ubuntu 184.108.40.206 OS. Now I cannot use apt-get update because of the follow error:
W: No sandbox user '_apt' on the system, can not drop privileges
E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?
Then when I go to Virtualmin web tool. This error shows:
Error - Perl execution failed
Can't locate lib.pm in @INC (you may need to install the lib module) (@INC contains: /usr/share/webmin /etc/perl /usr/local/lib/perl/5.18.2 /usr/local/share/perl/5.18.2 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.18 /usr/share/perl/5.18 /usr/local/lib/site_perl . /usr/share/webmin/ ..) at /usr/share/webmin/authentic-theme/index.cgi line 14.

Please help. All of my services are there.
