The Copying the source file error has been around for a while - it's a bug in the regex used by Jenkins to pick up on the warnings (and couldn't cause the actual validation errors in any case). I've now fixed this.

In regards to the unable to reach remote location error, we recently rebuilt the SUSE images, so this is probably a regression or other issue in the Appstream tools themselves (like wanting specific headers, or lacking SSL support). The CI scripting has not changed recently, at least not in regards to the Appstream components.

Thoughts?

Any comments on the above?

Not in the appstream data business myself. @apol or @mak do you have an idea?

Which version of AppStream do these SUSE images use? In older versions, AppStream was making only header requests, which some webservers did not allow. So newer versions try to download the first byte of a document instead, which should always work.

The package version should be visible in the Docker image build log on Jenkins. Given this has regressed recently though it's more likely a newer version is the cause here as it only showed up when we rebuilt the image.

Ping?

The particular code hasn't been touched in any recent AppStream version, and as far as I can see (at least from the log I found when searching on Jenkins), your AppStream is up to date.
So, I guess it's something else in the image that is broken (especially since this seems to work on other images, I would look for the images generally having no network access, or for some recent curl updates). If appstreamcli is run with the --nonet flag, all actions that require network access are disabled, which can be used as a temporary workaround.
