I have been getting this issue for over a week now. I have looked everywhere but I haven't found any solution that could help.
I have changed my source.list according to the official site. I used different mirrors manually. I switched ipv6 off and used ipv4 only
but nothing seemed to help. I don't want to reinstall the OS. Please help.
