I have installed VPN Unlimited as I have a lifetime subscription.
Unfortunately, when it is started, the internet does not work, Google does not even open.
I tried to switch servers but nothing.
I installed it with Software, but now I can't find it anymore and I don't know how to uninstall it.
Can anyone tell me how to do it?
Also, your screenshot shows that the Repository does not have a Focal Release File. You need to ensure that you remove that Repository from your sources.list.d directory.
Double click on the installation package, so I opened "software" with VPN Unlimited to uninstall.
I uninstalled the application. Then with Stacer I performed the complete uninstall and deleted the focal release file from the repository.
