I have upgraded to artful recently and cannot install
r-recommended any longer. I keep getting this error message:
user@box:~$ sudo apt install r-recommended [sudo] password for user: 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-recommended : Depends: r-cran-boot (>= 1.2.19) but it is not going to be installed E: Unable to correct problems, you have held broken packages. user@box:~$
Nonetheless, https://cran.r-project.org/bin/linux/ubuntu/artful/ is already available.
Edit: As asked by @muru in the comments, the output from
sudo apt-get update plus the output from
sudo apt-get upgrade were
