Accidently I have removed settings and now any ways to get back with our internet, maybe deb file? I have a problem wifi settings and can't see the settings. Thanks everyone.
Which files have you removed?
And just in case you mean that you don't have access to the settings menu, you can launch the settings by running this in a terminal:
gnome-control-center
I am sorry I don't know exactly but removed some apps for cleaning purpose. Now cant find settings. And can't find your mentioned cmd too. Even can't access internet.
It's possible that some of the programs you removed had some system libraries listed as dependencies, and removed those as well. So, what were you trying to clean up?
You can also look inside the /var/log/apt/history.log and /var/log/apt/term.log files, to see the latest activity generated by APT (the package manager).
