You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 libnsl-dev : Depends: libnsl2 (= 1.3.0-3build3) but 1.3.0-2build2 is installed
 locales : Depends: libc-bin (> 2.39)
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or 
specify a solution).
