If I use update command from terminal or synaptic or software-updater then I ownership automatically changes without doing anything and also error notification disappears.

What can I do?...

Does the system microphone and camera work in xcp-ng?

Okay in my case also I am unable to use the system mic. I don't know if earphone mic will work as I haven't tested.

I tried as much as possible from my side.

I am using Ubuntu 20.04.2 (64-bit) as host and Q4OS(32-bit) as guest. I have added camera from USB host devices and hence it works now on using google meet in virtual machine.


But I am still...

And is it possible to use the system microphone i.e. the one with laptop?

Yes it's name appears as Virtual Machine Manager and I got it by installing the apt virt-manager.

In virt-manager and kvm how can I use microphone in order to use google meet?

In synaptic I checked

No I frequently use that autoremove command and still I have some packages of 53 version. Also is there any way to correct the system packages in case I have removed anything which I need actually.

Btw do I need all the linux-modules, image versions or having one is sufficient? I have 5.8.0-53, 5.8.0-55 and 5.8.0-59

I just thought that since I signed the modules in order to use those, now I too have to unsign those in order no longer to keep those in use. However I have no idea and it's just a guess and nothing....
