It’s been 1 month now, every time I run

sudo apt-get update

I get the following error:

I tried using the following commands to solve:

sudo apt-get clean

And the error still persists, I can’t even install anything because I always come across this error, kindly help me solve.

Errors:

• Failed to fetch http://apt.pop-os.org/ubuntu/dists/jammy/universe/source/Sources.xz – This is the main error. The file seems to have an unexpected size, which might be due to a temporary inconsistency on the Pop!_OS server.
• Failed to fetch (multiple lines) – These errors are consequences of the main issue and indicate that other files related to package information couldn’t be downloaded.
