I'm trying to install the g++ compiler on Ubuntu 22.04.1 LTS, and I get the following:

$ sudo apt-get install g++

Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help resolve the situation:

The following packages have unmet dependencies:
 libc6-dev : Depends: libc6 (= 2.35-0ubuntu3) but 2.35-0ubuntu3.1 is to be installed
E: Unable to correct problems, you have held broken packages.

Running

$ dpkg --get-selections | grep hold

returns me nothing at all. I am new to Linux, so I have no idea what to do next.

Does anyone know how to resolve this issue?

Regards, -- DrB.

UPDATE 1: I tried

$ sudo apt install build-essential

but that gave me the exact same result.

UPDATE 2: I downgraded libc6 as follows:

$ sudo apt install libc6=2.35-0ubuntu3 libc-bin=2.35-0ubuntu3

after that, the command

$ sudo apt-get install g++

worked just fine.

HOWEVER: notepadqq NO LONGER WORKS.

The question now is... how can I find out what else I broke by doing this?

  • Nope. Tried all that. That's a 10-year-old thread, by the way. (why can't I insert newlines into this comment?) The issue is that g++ depends on libc6 v.3, but v3.1 is already installed, and I assume it's installed for a reason, so I don't want to mess with it unless someone can verify that it won't break anything if I do... – DrB Mar 30 '23 at 22:50
  • To answer your new question from the latest edit at the end of your question please install the notepadqq snap package using sudo snap install notepadqq It works OK. 2. Please refer to How to prevent updating of a specific package?
