On two Ubuntu Servers one 18.04.6 and the other 20.04.4
Manually responded to update alert inside Webmin, clicked to update to 1.995 - got:

Then lost connectivity. From command line, with the restart failed, as root:

Restarted fine with :

service webmin start

Thanks. We are aware of that and working on a fix. Also, it was already reported.

Anyone installing Webmin 1.995 please run updates via console.

[Earl Daniels]

Another server of mine, also an LXC container running Ubuntu 18.04.6, apparently ran the auto upgrade cron with no problems.

Thank you for the prompt reply and the great control panel!

[Ilia]

Thank you for your kind words. I promise we're gonna nail this bug and eventually support properly both old and new systems (using systemd).

There appears to be a new and more complicated unit file which fails to start for me on 2 RPM systems - Opensuse and Centos. I see now it's also now in Debian, not rebooted to try that yet.

NEW - fails to start

[Unit]
Description=Webmin server daemon

[Service]
Environment="PERLLIB=/usr/libexec/webmin-1.996"
ExecStart=/usr/libexec/webmin-1.996/miniserv.pl /etc/webmin/miniserv.conf
ExecStop=/bin/kill $MAINPID
ExecReload=/bin/kill -USR1 $MAINPID
PIDFile=/var/webmin/miniserv.pid
Type=forking
Restart=always
RestartSec=2s
TimeoutSec=15s

[Install]
WantedBy=multi-user.target

OLD - simpler and still works. I swapped out the new for old as I need webmin working.

Description=Webmin server daemon
After=syslog.target

[Service]
ExecStart=/etc/webmin/.start-init
ExecStop=/etc/webmin/.stop-init
PIDFile=/var/webmin/miniserv.pid
Type=forking
KillMode=none

[Install]
WantedBy=multi-user.target

Are there significant advantages of the new more complicated version ?

[Jamie Cameron]

Richard Farthing - what error did you get when trying to start Webmin with the new unit?
