As I already pointed out in another thread to which no one responded, https://forum.qubes-os.org/t/upgrade-to-4-3-error-during-3rd-stage-protected-package-dnf/39050/2, the problem persists. The update script gives me the same error:
Errors during downloading metadata for repository 'qubes-dom0-cached':
- Curl error (37): Couldn't read a file:// file for file:///var/lib/qubes/updates/repodata/repomd.xml [Couldn't open file /var/lib/qubes/updates/repodata/repomd.xml]
Error: Failed to download metadata for repo 'qubes-dom0-cached': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried
Ignored repositories: qubes-dom0-cached
Package xfce4-screensaver-4.18.4-4.fc41.x86_64 is installed.
Dependencies resolved.
No action required.
Done!
I cannot understand why the script was released in the official version if it is so buggy and still needed to be tested. And I don’t understand why the developers are not intervening to help the many users who are experiencing the same problems. This thread has also ended without a working solution, it seems to me.
