package information could not be initialized

[Jimmy Biel]

(title translated from German: "Packetinformationen konnten nicht initialisiert werden")
I got this message on boot-up and it says i should include the following into this report:
E:can not open /var/lib/apt/lists/de.archive.ubuntu.com_ubuntu_dists_focal-backports_InRelease - fopen (13: Keine Berechtigung), E:Die Paketliste oder die Statusdatei konnte nicht eingelesen oder geöffnet werden.

"Keine Berechtigung" = Access denied
"Die Paketliste oder die Statusdatei konnte nicht eingelesen oder geöffnet werden." = The packagelist or statusfile could not be read or opened.

I am using this ubuntu version: Ubuntu 20.04.3 LTS
I did not want to perform a distribution upgrade

As to 3) and 4)
i did not expect anything, as i just started the computer and got the error described above.

Please sudo chmod 644 /var/lib/apt/lists/de.archive.ubuntu.com_ubuntu_dists_focal-backports_InRelease to fix this.

If you can reproduce this reliably, please let me know. Otherwise, there's nothing we can do to fix the underlying bug, as we can't analyse it further, so I'm going to be closing the bug. We get about 3-4 such reports per year I think.
