idk , internet is working fully but there is that problem ( showing exclamation marks)
i cant install anything sadly . even i cant install vlc . why this is happening with zorin os ?
Open Software & Updates and on the first Tab set the Source to Main Server:
and then make a sudo apt update && sudo apt upgrade
You could try this solution in the terminal:
sudo rm /var/lib/apt/lists/* -vf
sudo apt-get update
[Source: [ubuntu] Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailab]
Go to Settings>Privacy then toggle connection checking on then off (or vice-versa).
That should get rid of the "?" (but it may come back next boot)
i tried resetting , nothing happens
