I am trying to install R on Ubuntu. I'm relatively new and inexperienced so may have made a stupid mistake. I am running Ubuntu 19.04

I am installing R using apt: sudo apt-get install r-base

When I run this I get this error:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
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.
 r-base : Depends: r-base-core (>= 3.6.3-1bionic) but it is not going to be installed
          Depends: r-recommended (= 3.6.3-1bionic) but it is not going to be installed
          Recommends: r-base-html but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

I have looked at this question: How do I resolve unmet dependencies after adding a PPA? for assistance.

I have run

  • sudo apt-get update
  • sudo apt-get upgrade (0 to upgrade, 0 to newly install, 0 to remove and 0 not to upgrade.)

These run with no issues.

I have then run sudo apt-get -o Debug::pkgProblemResolver=yes dist-upgrade

This responded with:

Reading state information... Done

The following packages have been kept back:
  wine-stable
0 to upgrade, 0 to newly install, 0 to remove and 1 not to upgrade.

I therefore removed and reinstalled wine-stable. When rerunning debug I no packages showed.

I believe my issue may be due to something in my PPA. I disabled a couple of these.

The output of cat /etc/apt/sources.list is:

Through Software & Updates -> Other Software, I unticked a couple of items which I may have helped or worsened stuff:

I hope I have included anything which may be helpful. Let me know if you need more detail.

  • You appear to be trying to use the bionic-cran35 repository in disco - I'm not sure that's a good idea – steeldriver Mar 24 '20 at 16:29
  • Aha okay - I can't remember intentionally setting this. Could you assist me with why this is a bad idea and alternatives/rectifications, please? – Allentro Mar 24 '20 at 16:31

This is a simple fix. bionic-cran35 is trying to run as it is present in the source.list. This is from a previous botched attempt at installing. Commenting out the 

deb https://cloud.r-project.org/bin/linux/ubuntu bionic-cran35/

line in the code has fixed this ptoblem.

Bionic is from previous Ubuntu distributions and has been replaced by Disco in 19.04.

Thank you to @steeldriver for pointing out my flaw.
