Raspberry Piのapt-get upgradeでvlcが壊れてるエラーが出る問題の対処

問題

Raspbian Bullseyeになってからか、初回セットアップ時のapt-get upgradeでエラーが出るようになった。vlcが壊れてるらしい。vlcなんて使わないのだけど、これのせいでupgradeができない。

まずはupdate。

$ sudo apt-get update
Hit:1 http://raspbian.raspberrypi.org/raspbian bullseye InRelease
Hit:2 http://archive.raspberrypi.org/debian bullseye InRelease

ここまではOK。次、upgrade。
