So, I just ran into this after my VM ran out of space. I removed all of
the reports from /var/lib/puppet/reports# to free up space and then
restarted the server. After the restart, I could run the following
$ sudo service apache2 start
* Starting web server apache2 [ OK ]
$ sudo service puppetmaster start
* Starting puppet master [ OK ]
$ sudo service puppet-dashboard-workers start
* Starting Puppet Dashboard Workers
but had the same errors as OP.
ERROR: there is already one or more instance(s) of the program running
ERROR: there is already one or more instance(s) of the program running
* Puppet Dashboard Worker (pid ) is not running
Puppet dashboard in Open Source was showing up when I went to the website,
but my 3 dev nodes were unresponsive and it just kept building up pending
tasks.
I followed the steps Gary did by removing the pid and also deleted the .log
files located in /usr/share/puppet-dashboard/tmp/pids.
puppet --version 3.8.3
puppet dashboard 1.2.23
