Install R and RStudio on Ubuntu 19.10 with essential libraries for data science. Based on pachamaltese/r_ubuntu_17_10.sh (for Ubuntu 17.10). Note: You need to make sure the default library location - /usr/local/lib/R/site-packages - is writable .

I've got unmet dependencies as following:

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
r-base-dev : Depends: r-base-core (>= 3.6.3-1bionic) but it is not going to be installed

Any help is appreciated.

OS:Ubuntu 19.10

It fixed after editing sources.list sudo gedit /etc/apt/sources.list file and removing added cran repository, I mean this line deb https://cloud.r-project.org/bin/linux/ubuntu bionic-cran35/;

You perhaps have to change the last part of sudo add-apt-repository 'deb https://cloud.r-project.org/bin/linux/ubuntu eoan-cran35/' in relation of your ubuntu version. If you don't have the last version —eoan— will fail.

My Ubuntu version is 19.10, What was I supposed to do?
How can I find a related repository link?

@mberneti I just put it. Your version it eoan.

@luispuerto oops ...
Thank you.
