Before all, i am sorry if this problem is asked a lot already. I tried the solutions available in other’s thread and nothing just work for me. Also, i’m really new at linux (just installed kubuntu yesteday) so i may trip over a little thing a lot.
So, my problem is when i do anything related to update, upgrade, and install, i always get answers like this:
Err:4 http://id.archive.ubuntu.com/ubuntu bionic-updates InRelease
Connection failed [IP: 91.189.88.142 80]
also in the end:
W: Failed to fetch http://id.archive.ubuntu.com/ubuntu/dists/bionic-updates/InRelease Connection failed [IP: 91.189.88.142 80]
W: Some index files failed to download. They have been ignored, or old ones used instead
Can anyone please provide solution? My internet works fine when browsing. I also use snap to install discord and it work fine. Thanks.
