gdb Installation Error -- libc6-dev

mq flag

UPDATE: I have re-installed (3 times) Ubuntu, and performed sudo apt policy libc6 libc6-dev with this output:

libc6:
  Installed: 2.35-0ubuntu3.1
  Candidate: 2.35-0ubuntu3.1
  Version table:
 *** 2.35-0ubuntu3.1 100
        100 /var/lib/dpkg/status
N: Unable to locate package libc6-dev

I then did a sudo apt update and another sudo apt policy libc6 libc6-dev and got this output:

libc6:
  Installed: 2.35-0ubuntu3.1
  Candidate: 2.35-0ubuntu3.1
  Version table:

I then was able to perform sudo apt-get install build-essential gdb g++ successfully.

Thank you @steeldriver for looking into this issue with me. I don't know how to close this Question; I suppose the Moderators will eventually do that. Cheers!!


I am running into the same problems as stated in an older question (July 2018), but now (Dec 2022) with a newer version of Ubuntu (22.04 LTS).

When installing the g++ compiler and gdb debugger using sudo apt-get install build-essential gdb g++ I get the following output, with an error for libc6-dev :

Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
gdb is already the newest version (12.0.90-0ubuntu1).
gdb set to manually installed.
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 to 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.

This is the output of cat /etc/os-release

The last comment offered by user Olimjon in that question recommends a clean installation of Ubuntu, which I have done twice, but the problem persists.

Ultimately, my goal is to follow the tutorial on OpenGL by Victor Gordan, however, I am not able to compile and run the examples successfully.

Any suggestions on how to repair the libc6-dev dependencies?

Have you modified your repository sources - for example enabling and then subsequently disabling the `jammy-updates/main` repository?

@steeldriver - No, I have not modified anything.
hr flag
OK well please [edit] your question to include the output of `apt policy libc6 libc6-dev`
hr flag
Your apt policy outputs look weird - like you don't actually have ANY repositories enabled (as though your `/etc/apt/sources.list` file is empty or all commented out)

@steeldriver -- you are correct, my bad. I was in the middle of following the instructions in that other question. I have updated the output of 'apt policy libc6 libc6-dev'. Sorry!!
hr flag
OK so **somehow** you have managed to install a newer version of libc6 (2.35-0ubuntu3.1) than is available in your **currently configured** sources (jammy/main). Does jammy-updates/main appear in your sources.list? Was it added at some point then commented out?

I have added the contents of `sources.list`. And also, in case it is relevant, I am using a USB drive for the installations.

Looks like I have the same problem (libc6 2.35-0ubuntu3.1 is installed but the corresponding "jammy-updates" repo is not enabled, therefore libc6-dev cannot be installed later). And https://askubuntu.com/questions/1434778/cant-install-libc6i386-on-jammy and https://askubuntu.com/questions/1429323/ubuntu-22-04-issue-cannot-install-libc6-dev-you-have-held-broken-packages look like that as well. My current guess is that this is a bug in Ubuntu or in some 3rd-party repository (maybe in Nvidia repo?). I'll try to find out more.

No idea what caused this. The upgrade from libc6 2.35-0ubuntu3 to 2.35-0ubuntu3.1 was installed a few days after we installed this host; and /var/log/apt/history.log.3.gz just gives "Commandline: aptdaemon role='role-commit-packages' sender=':1.112'" as the reason. Btw. we have the 3rd-party repos from docker.com and nvidia.github.io enabled; maybe that made a difference. I've enabled the jammy-updates repo now, and that fixed it for me (I can install build-essential now).
I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
