[R-sig-Debian] Disco Dingo repository issues

[Willem Ligtenberg]

Hi,

I have just installed Ubuntu 19.04 (Disco Dingo) and after adding the following repo:
deb https://cloud.r-project.org/bin/linux/ubuntu disco-cran35/
and importing the keys, I want to install r-base so I perform the following:

sudo apt update
sudo apt install r-base

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 (>= 3.6.0-1cosmic) but it is not going to be installed
          Depends: r-recommended (= 3.6.0-1cosmic) 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.

It seems Disco Dingo packages have references to their Cosmic Cuttlefish versions.

When trying to install r-base-core first I get the following issue:
sudo apt install r-base-core r-base

The following packages have unmet dependencies:
 r-base-core : Depends: libicu60 (>= 60.1-1~) but it is not installable
               Depends: libreadline7 (>= 6.0) but it is not installable
               Recommends: r-base-dev but it is not going to be installed

I am willing to help/test to resolve these issue.

Kind regards,
