```auto
The following packages have unmet dependencies:
 libc6-dev : Breaks: libgcc-8-dev (< 8.4.0-2~) but 8.3.0-6+rpi1 is to be installed

```

But this is indeed a known error. Same happened in several other cases:

- [Issue with apt full-upgrade when upgrading to bullseye](https://dietpi.com/forum/t/issue-with-apt-full-upgrade-when-upgrading-to-bullseye/5974)
- [Failed to upgrade from Debian Buster to Bullseye - #10 by alleyu2](https://dietpi.com/forum/t/failed-to-upgrade-from-debian-buster-to-bullseye/5712/10)
- [Updating to Bullseye · Issue #4857 · MichaIng/DietPi · GitHub](https://github.com/MichaIng/DietPi/issues/4857)
- …

So worth it if it prevents users from some upgrade trouble. It is definitely a Buster package, and development headers, so safe to purge.
