It seems like http://ua.archive.ubuntu.com is down.
Im an trying
sudo apt update but it says
Cannot initiate the connection to ua.archive.ubuntu.com:80
Is there any website with servers status, and info when it will be repaired?
Also it says
W: Some index files failed to download. They have been ignored, or old ones used instead.
How I can fix this issue? Should I just use mirror server from another country?
