I am new to linux. I have been using elementary OS for about 15 days now. Everything was fine until few days ago when suddenly I could not connect to ubuntu repositories.
- Using the "select best server" in softwares & updates does not work
- Manually adding ubuntu repositories with sudo add-apt-repository does not work.
The following is the result of sudo apt update.
W: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/bionic/InRelease Connection failed [IP: 22.214.171.124 80] W: Some index files failed to download. They have been ignored, or old ones used instead.
But if I ping 126.96.36.199, I get reply.
