so I tried to update ubuntu 21.10 on raspberry pi using terminal and it says this error:
Err:7 http://ca.archive.ubuntu.com/ubuntu impish/universe arm64 Packages
404 Not Found [IP: 2001:67c:1562::15 80]
please help me fix this
edit: I already tried changing the sources to port but it keeps on showing this error
here is the whole terminal text if it helps:
