I tried to upgrade from Ubuntu 16.04 to 18.04 using sudo do-release-upgrade -d Everything was downloaded without any problem but ran into error while extracting and upgrading. I tried rebooting but now it is stuck in login loop. I tried to correct dependencies but it didn't work. enter image description here

  • you need sudo apt-get -f install (you didn't have sudo), plus try sudo apt-get dist-upgrade (it doesn't have the restrictions of upgrade). If you still get problems you need to check your sources.list file (https://packages.ubuntu.com/search?keywords=libc-bin & https://packages.ubuntu.com/search?keywords=libc6 as I agree with error messages) – guiverc May 04 '18 at 10:09
  • I have used sudo apt-get -f install as well. Plus, sudo apt-get dist-upgrade is also giving same error – RD017 May 04 '18 at 10:23
  • I would look in your sources.list file (maybe grep bionic /etc/apt/sources.list) and expect to see something missing. eg. my own shows deb http://[redacted-mirror]/ bionic main multiverse universe restricted (you may not have all, but look for 'main' esp., likewise bionic-updates, bionic-security..) – guiverc May 04 '18 at 10:26
  • I already have these. The problem is due to unmet dependencies which I am unable to get. – RD017 May 04 '18 at 10:39
  • the bionic version of libc-bin (https://packages.ubuntu.com/bionic/libc-bin) has a rule that libc <<2.28 so 2.27 complies. Your error message says <2.24 which is a xenial condition (https://packages.ubuntu.com/xenial/libc-bin). Your sources.list file isn't correct. If you grep xenial /etc/apt/sources.list you should get no results, but I bet you do due to errors in your sources.list file (# or commented out lines are okay) the same grep but with bionic (18.04) should get many many lines (my prior comment where I only listed 1 of the many lines you'd see) – guiverc May 04 '18 at 10:46
  • No results for xenial, and there are results for bionic – RD017 May 04 '18 at 10:55
  • Can you please add lsb_release -a, and grep "^deb.*bionic" /etc/apt/sources.list to your question (edit it and add the commands and results there please). To me it still reads as if you have errors in your sources.list file(s). This grep only displays lines beginning in 'deb' followed by 'bionic' (Sorry, as I realize you've said this is your error all along - I can't think of any other cause) – guiverc May 04 '18 at 10:58

    lsb_release -a is showing that I have bionic installed, but login screen is of xenial. I think I messed up and ended between both. I will go with a fresh install now. Thanks for your efforts :) – RD017 May 04 '18 at 11:11
  • Reviewers - please read the whole screenshot... it's not a duplicate of that! – Zanna May 05 '18 at 16:04
  • Possible duplicate of Permission denied, are you root? – waltinator May 06 '18 at 00:19
  • See the second last line. I think you should use "apt-mark showhold" to see if some packages are held. You can unhold them, then try "sudo apt-get -f install" – alfred Sep 17 '18 at 11:17

    Does this answer your question? Ubuntu gets stuck in a login loop – karel Mar 11 '20 at 07:07

I solved this by logging in via command prompt then entering the command:

sudo ubuntu-drivers autoinstall

This installed the correct NVIDIA GPU drivers and then it worked fine after restart.
