I have the following problem:

I had to mingle with some libs to build a project successfully. After I rebuild one of those libs (libtirpc) something broke and I was not able to either sudo nor use apt or other tools to somehow restore the old libtirpc version.

Now I am not even able to reboot anymore.

Can I use a live USB with the same Ubuntu ISO (Ubuntu 22.04.3) start a live session mount the root partition of my broken installation and then chroot into that?

Can I then use the live sessions sudo rights and e.g. apt, to reinstall libtirpc to the broken installation?

I have never used chroot and would be grateful for some insights before I cause even more damage!

"Can I use a live USB ... Can I then use the live sessions sudo ..."? ... Yes, and Yes, but your results may vary ... See for example https://askubuntu.com/a/1238393 ... And you will have root powers so no need for sudo in the chroot – Raffa Sep 07 '23 at 16:41
Thank you very much, then I will try that and hope for the best. – Strohhut Sep 07 '23 at 16:56
You don't really even need a chroot - you could use apt's RootDir option from the live session directly. See How to re-insall libc6 after remove? – steeldriver Sep 07 '23 at 17:15
