My linux skills are rather limited, so I hope someone can point me in the right direction.
Some time ago, I setup my webserver by running http://software.virtualmin.com/gpl/scripts/install.sh on Ubuntu Server 16.04. This installed Webmin 1.881, Virtualmin 6.03 and Usermin 1.741. Until today, this has all worked fine.
However, this morning the dashboard showed that there were 5 updates to Virtualmin packages available. They were: dovecot-imapd 2.2.22-1ubuntu2.8 dovecot-pop3d 2.2.22-1ubuntu2.8 postgresql 9.5+173ubuntu0.2 postgresql-client 9.5+173ubuntu0.2 webmin 1.890
After installing them by clicking the Install All Updates Now button, I can no longer create a virtual server.
The first time I tried, I got the error message: Failed to create virtual server : Mailman cannot be enabled unless the administration list mailman has been created. I then noticed that there was an additional feature in the Enabled features list called Allow Mainman mailing lists. I unchecked this option, and tried again.
After unchecking this option (I don't use it anyway) I tried again, and this time I got the error: Failed to create virtual server : New virtual server has no IP address! Perhaps Virtualmin could not work out the system's default IP. I then noticed that in the IP address and forwarding part, it was set to Shared, on IP, but it did not show the servers default IP address.
Is there a way to work around this, or if not, is there a way to revert the updates? Preferably without messing-up the virtual servers that are currently running.
Kind regards, Bert
