Installing g++ wants to upgrade your version of libc6 2.35 by a minor 
build number.


I'm running 22.04 (but... a KDEneon version, so not pure Ubuntu). Looks 
like g++ has been installed, so when I tested it I could not recreate 
the problem.


Try:

apt dist-upgrade
apt-policy libc6 libc6-dev g++


The apt-policy helps inspect versions installed vs available.

Also, see `man apt-permissions` for syntax and semantics of apt search 
patterns.

i.e. `apt list ?broken` to see if any existing packages are "broken".


In this case, it may be worth doing the --force as Peter suggested 
(depends on how much it would hurt if the installation gets broken).



Quite an interesting situation - keep us updated!
