Hello again @Flox .
As i was gathering all the logs as requested, i accidentally found a way to make sure it works, at least if you’ve never used samba before upgrading.
Samba did start fine from he terminal before i let rockstor touch it after reinstalling. That got me thinking about what you said about the “Set the Workgroup in the wrench”. This time, before attempting to start samba, i went to the wrench and typed in my workgroup: Samba fired up just fine.
Thinking this was a fluke, i set up another VM and retried, but this time i started samba without the Workgroup: sure enough it kept giving errors as before, even if i tried inputing the workgroup after it would not work.
The trick is then:
For this version (3.9.1-16), do not use Samba at all before upgrading, and then make sure to set the Workgroup in the Services Tab by clicking on the Wrench icon BEFORE starting samba. As @Flox said, this version has a glitch that starts samba automatically after doing that, so there’s no need to re-turn it on after setting the workgroup.
@Flox Thank you for the help provided! I still have the broken VM available if you still want me to test out anything else.
Again, thank you for your time!
