Having an issue updating Ubuntu 18.04 install

sudo apt update

works fine, then

sudo apt upgrade

fails with

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

then running:

sudo apt --fix-broken install

gives

    Please add output of apt-cache policy libgdk-pixbuf2.0-0:amd64 libglib2.0-0 to the question. – N0rbert Jan 28 '19 at 08:42

    For me it seems that you have not enabled bionic-security and bionic-updates pockets of repositories. Please enable them and retry with sudo apt update, sudo apt full-upgrade. – N0rbert Jan 28 '19 at 08:51
  • Try my updated answer. – N0rbert Jan 28 '19 at 09:02
  • Thanks - I get the same error as before: "dpkg: error: parsing file '/var/lib/dpkg/status' near line 14881 package 'libgdk-pixbuf2.0-0:amd64': " - the line in questions reads "Depends: libc6 (>= 2.14), libglib2.0-0 (6= 2.48.0), libjpeg8 (>= 8c), libpng16-16 (>= 1.6.2-1), libtiff5 (>= 4.0.3), libx11-6, shared-mime-info, libgdk-pixbuf2.0-common (= 2.36.11-2)" – pete Jan 28 '19 at 09:09
  • Then install Aptitude with sudo apt-get install aptitude and then run sudo aptitude dist-upgrade to fix the problem. Or run sudo apt-get dist-upgrade. – N0rbert Jan 28 '19 at 09:18

    Thanks for your help - I fixed it by editing the /var/lib/dpkg/status file and changing libglib2.0-0(6=2.48.0) to read (=2.48.0) - then did an apt update/upgrade – pete Jan 28 '19 at 09:35

Try to download both problematic packages and then force their installation with:

apt-get download libgdk-pixbuf2.0-0=2.36.11-2 libglib2.0-0=2.56.3-0ubuntu0.18.04.1
sudo dpkg -i --force-all lib*.deb

I fixed it by editing the /var/lib/dpkg/status file and changing libglib2.0-0(6=2.48.0) to read (=2.48.0) - then did an apt update/upgrade
