i am unable to update zorin os internet is connect but every time it says internet not connected how i fix this?
Can you open a terminal and run
sudo apt update
and post the output here?
It's probably a bad repository that is giving a 404 error.
yes it is a bad repository how i fix this ?
I do not see any 404 errors in the screenshot you posted. Which repository is bad?
may be i am wrong i am not expert ..yesterday updates is almost completed and suddenly my laptop is shutdown when i again start software-update and still i face this issue ..
What happens if you run in terminal:
apt list -u
sudo apt upgrade
To solve the problem, you may need to run:
sudo rm -rf /var/lib/apt/lists/*
sudo apt-get update
Then run the Software Updater after completing that.
thanks bro problem solved ...
