Using this guide: How to upgrade Zorin 16.2 to a newer kernel
At the step:
> sudo add-apt-repository --remove "deb http://ca.archive.ubuntu.com/ubuntu jammy main"
> sudo apt install libssl3
I get lots of errors:
Get:1 Index of /ubuntu jammy/main amd64 locales all 2.35-0ubuntu3 [4,249 kB]
Err:2 Index of /ubuntu jammy/main amd64 libc6 amd64 2.35-0ubuntu3
Cannot initiate the connection to ca.archive.ubuntu.com:80 (2001:67c:1562::18). - connect (101: Network is unreachable) Cannot initiate the connection to ca.archive.ubuntu.com:80 (2001:67c:1562::15). - connect (101: Network is unreachable) Could not connect to ca.archive.ubuntu.com:80 (91.189.91.38), connection timed out Could not connect to ca.archive.ubuntu.com:80 (91.189.91.39), connection timed out [IP: 91.189.91.39 80]
My network (tethered through USB to phone is working fine (posting this response through that connection).
Any advice?
