[Resolved] appstream2 branch referencing stale commit

Tue, 24 Mar 2026 23:55:00 +0000

A mismatch between the appstream2 branch and delta indexes caused local Flatpak clients to fail to update appstream data. The issue is resolved now after regenerating both the branch and the indexes.

If you are still experiencing issues, please try the steps below to clear the local copy of the appstream2 branch. (01:33 UTC — Mar 25)

# For system-wide installation
sudo ostree --repo=/var/lib/flatpak/repo refs --delete flathub:appstream2/x86_64
# For user installation
ostree --repo=$HOME/.local/share/flatpak/repo refs --delete flathub:appstream2/x86_64
# Update the appstream data
flatpak update --appstream

Additionally, some client experienced timeouts when fetching delta indexes that were removed from the server. This was caused by the CDN not caching 404 responses, resulting in requests queuing up behind nginx’s cache lock. A fix was deployed to cache 404 responses, allowing clients to gracefully fall back to full downloads. (02:08 UTC — Mar 25)

[Resolved] CDN cache invalidation issue

Fri, 13 Feb 2026 05:38:00 +0000

Due to a brief downtime, one of the origin servers missed purging operation and was serving stale and non-existent index files. As a result Flathub builds failed while attempting to download dependencies and any general Flatpak clients experienced hangs or download failures.

The issue was resolved after the cache was invalidated. (07:00 UTC — Feb 14)
