Im on vult server. LiteSpeed CyberPanel installed. After updating to Ubuntu 23.04 I'm starting to getting this error when I try to update:

I read other posts, and checked sources.list and seems to be ok. Checked links and works fine.

I make a ping and get this error:

root@roble:~# ping us.clouds.archive.ubuntu.com
ping: us.clouds.archive.ubuntu.com: Temporary failure in name resolution
root@roble:~# ping ubuntu.com
ping: ubuntu.com: Temporary failure in name resolution

Any idea how to fix it?

Does this answer your question? [How can I get apt to use a mirror close to me, or choose a faster mirror?](https://askubuntu.com/questions/37753/how-can-i-get-apt-to-use-a-mirror-close-to-me-or-choose-a-faster-mirror)
I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
