KDE Linux is no longer pulling down the latest updates. I have used the verbose output of updatectl update and don’t know how to interpret it. I’ve included a screenshot of the output. Any help would be appreciated.

Similar here, though I get an HTTP 500 error when dowloading that .erofs file, rather than a timeout.
AFAIK http 500 is a server side error, so it is not a KDE Linux problem
It’s a server-side error, but the server is files.kde.org, which is why I’m posting about it on KDE Discuss.

Any logs?
Originally I got a very similar output to OP’s, except with an HTTP 500 error on place of the timeout error. I didn’t save the full log, sorry.
When I retry, I’m now consistently getting the same behaviour as OP, with the timeout. Full log below in text format.

(sd-pull-raw) failed with exit status 1: Input/output error
I was able to fix this by disabling delta updates:
sudo systemctl disable --now kde-linux-sysupdated.socket
Perhaps the “Troubleshooting & known issues” page above should be updated to mention the problems with delta updates. At present it says:
If updates fail between 30% and 40% with “Input/output error”, wait an hour or two and try again. This is likely to be a known issue related to updates being advertised as available before all update servers have fully synced.
But retrying made no difference to this issue. No update ever succeeded on this machine until I turned off the deltas.
