Package repository changes not possible in Ubuntu?

SYSTEM INFORMATION
OS type and version Ubuntu 24.04.4
Webmin version 2.630

Hi, I see the buttons that appear to allow for enabling/disabling/deleting package repositories, but there is no way to select any of the rows and therefore the buttons don’t work:

At minimum, it would be useful to be able to manually change the repository URLs via Webmin to allow for a system upgrade to the next major OS release. And ideally it would be nice to have a “System upgrade” tab that runs the appropriate apt dist-upgrade command on Debian systems, or specifically for Ubuntu maybe do-release-upgrade as described in How to upgrade your Ubuntu release - Ubuntu Server documentation.

You might want to use the copy link on the Dashboard upper right corner to supply more information.

I have the boxes but the ‘trendy’ design makes them harder to see for us sight impaired seniors. :wink: Seriously, there is a difference between glaring and useful. (I’m using Opera on Debian 13)

Interesting, thank you, so it does work for Debian.

Weird, I wonder what’s wrong with my installation?

Could be your browser. Have you tried something else?

I don’t think ARM is specifically supported. I could be wrong.

Nothing is wrong. Starting with Ubuntu 24.04, Ubuntu no longer uses the old .list repository format by default. It now uses the newer deb822-style .sources files instead.

Editing these repos isn’t supported yet in Webmin UI.
