You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 libc6-dbg : Depends: libc6 (= 2.31-13+rpt2+rpi1+deb11u5) but 2.31-13+rpt2+rpi1+deb11u4 is installed
 libc6-dev : Depends: libc6 (= 2.31-13+rpt2+rpi1+deb11u5) but 2.31-13+rpt2+rpi1+deb11u4 is installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).```
