Does `sudo apt install --reinstall python3-apt` fix the issue?

Sadly Not, this results in: root@Pi-Hole:~# sudo apt install --reinstall python3-apt E: Could not open lock file /var/lib/dpkg/lock-frontend - open (74: Bad message) E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), are you root? root@Pi-Hole:~#

If you are sure there's no running process, that is, if you have killed the process (apt or dpkg) that was running the update, then you can delete the lockfile: `sudo rm /var/lib/dpkg/lock-frontend` and then run apt again.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
