  • Seeing the Unable to lock directory indicate that there are 2 update processes that block each other. Have you tried waiting for a while and then trying it again? – Peter Uithoven Feb 12 '19 at 7:38
  • oops.sorry actually i posted wrong image, This is the actual error "....E: Failed to fetch packages.elementary.io/appcenter/dists/bionic/main/dep11/… File has unexpected size (248094 != 298652). Mirror sync in progress? [IP: 104.28.5.44 80]...." You the size is miss match 64x64 icon. I tried -rm the sources.list but not helped – Rajesh Sarker Feb 12 '19 at 8:42
  • Could you update the image in the question as well? To keep things clear. Could you run the following command, it should give a list of your software sources grep -r --include '*.list' '^deb ' /etc/apt/ | sed -re 's/^\/etc\/apt\/sources\.list((\.d\/)?|(:)?)//' -e 's/(.*\.list):/\[\1\] /' -e 's/deb http:\/\/ppa.launchpad.net\/(.*?)\/ubuntu .*/ppa:\1/' Please include the result in your question. – Peter Uithoven Feb 12 '19 at 9:04

As the log says, it may have been because the mirror was stuck while syncing. If you run your original sudo apt update command it should now be fine.

If an error still occurs, you can try removing the apt cache with the following command:

sudo rm -r /var/cache/apt/* /var/lib/apt/lists/*
