Question

Ubuntu 20.04 LTS to 22.04 LTS has crashed update/upgrade fetch

I was following this tutorial(https://www.digitalocean.com/community/tutorials/how-to-upgrade-to-ubuntu-22-04-jammy-jellyfish) and I managed to upgrade to Ubuntu 22.04 with no problem.

Then after some time I was going to my personal WordPress page admin and wanted to install a new plugin and I saw this big red message stating “An unexpected error occurred. Something could be wrong with WordPress.org or the way this server is configured. If the problem persists, try asking in the support forum.” Image --> https://imgur.com/a/5th6vMI

Then I saw that **CURL **does not seem to be working on the server when I looked in Site Health Section Image --> https://imgur.com/a/dqmWGQF

Then I tried to update and upgrade on the server with no result with the error stating “Failed to fetch”. Image --> https://imgur.com/a/c35Uvgu

Does anyone know maybe how I can resolve this error?

Best regards.

Hi @damir,

The curl: (6) Could not resolve host: error doesn’t mean you don’t have cURL installed on your droplet but that you can’t connect to the said website for a reason.

This could be a few things, like a firewall issue. Check your firewall (ufw/iptables) and see if everything is correctly set there.

Additionally, it’s possible there is a network configuration error like IPv6 being enabled or you using a Wrong DNS server.
