I'm trying to install GIMP with apt-get install on Ubuntu 18.04.1. It produces a dependency error:



$ sudo apt-get install gimp
Reading package lists... Done
Building dependency tree

Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
gimp : Depends: libgegl-0.3-0 (>= 0.3.0) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.


Following the chain of dependencies:



The following packages have unmet dependencies:
libgegl-0.3-0 : Depends: libumfpack5 (>= 1:4.5.2) but it is not going to be installed
libumfpack5 : Depends: libcholmod3 (>= 1:4.5.2) but it is not going to be installed
libcholmod3 : Depends: liblapack3 but it is not going to be installed or liblapack.so.3
liblapack3 : Depends: libgfortran4 (>= 7) but it is not going to be installed
libgfortran4 : Depends: gcc-7-base (= 7.3.0-16ubuntu3) but 7.3.0-27ubuntu1~18.04 is to be installed

E: Unable to correct problems, you have held broken packages.


The chain ends with gcc-7-base and gcc-8-base, both of which are already installed:



$ apt-cache policy gcc-8-base
gcc-8-base:

although under slightly different names that I can't decipher.



$ dpkg --get-selections | grep hold returns nothing, indicating that I have not, in fact, held any packages.



I've tried an update/upgrade/autoremove cycle. I've tried apt-get install -f. I've tried apt-get clean. None of these had any effect whatsoever.



I've installed Keybase and VS Code from PPAs. Other than that, this is a pretty fresh installation of 18.04, and I haven't done anything outside of the repos (or outside of apt-get install) except for those two things.



How do I figure out what the problem is, and how do I figure out how to fix it?



Edit: These repos are active in /etc/apt/sources.list:



deb http://us.archive.ubuntu.com/ubuntu/ bionic main restricted
deb http://us.archive.ubuntu.com/ubuntu/ bionic universe
deb http://us.archive.ubuntu.com/ubuntu/ bionic multiverse
deb [arch=amd64] https://packages.microsoft.com/repos/vscode stable main


and this in /etc/apt/sources.list.d/keybase.list:



deb http://prerelease.keybase.io/deb stable main


There are no others.

  • Can you post your apt sources files? Maybe you added a wrong repo which is for another version of Ubuntu.

  • Have you tried a simple sudo apt update before? Maybe something in the chain changed versions?

  • @davidbaumann Edited with that info. I don't think I've done that.
