I've been using Ubuntu for a couple months now but just recently the command sudo apt upgrade has stopped working. I get the error:

The following packages were automatically installed and are no longer required:

If you need any clarification on my problem please be specific. And also please dumb down all answers.

Thanks in advance

  • There should be at least one other error message above the line you copied. Please include the entire output of sudo apt upgrade.

Often these types of problems can be caused by non-standard sources, but here it looks like a package trying to be upgraded is conflicting with a file from the "no longer required" old libjpeg-turbo8 package.

These lines are the clue:

dpkg: error ... trying to overwrite '/usr/lib/i386-linux-gnu/libjpeg.so.8', which is also in package libjpeg-turbo8:i386 1.4.2-0ubuntu3

An easy fix should be to do what the earlier message says:

The following packages were automatically installed and are no longer required:

libjpeg-turbo8 libjpeg-turbo8:i386

Use 'sudo apt autoremove' to remove them.

So first Use 'sudo apt autoremove' to remove them, and then try again.

  • Hi. Thanks for your response. However, I have already tried this and it hasn't worked. Just to double check I tried again but the same result. Are there any specific packages I need to delete by any chance?

  • You definitely shouldn't be getting the same errors if the libjpeg-turbo8 libjpeg-turbo8:i386 packages have been removed... Are there still any files named /usr/lib/i386-linux-gnu/libjpeg.so.8 or it's x86-64 brother? Because they should have been removed as well

  • That's weird, if the files are gone there shouldn't be any problem writing new files... if the old packages weren't really removed (or purged even) then maybe dpkg still thinks the files are there, but I'm not positive on that. Have you tried apt remove libjpeg-turbo8 (without the extra :i386 and version) first, and what does it say? PS your google docs seems to only say "docs.google.com/document/d/…", but you can edit the info into your Q too
