I'm trying to install the R programming language on Zorin OS 16.3 Lite (the one with the xcfe desktop). I've been following the official installation instructions (linked below).
When I run
sudo apt-get install r-base
I get the following output:
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 (>= 4.3.1-4.2204.0) but it is not going to be installed
Depends: r-recommended (= 4.3.1-4.2204.0) 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.
After some troubleshooting I'm pretty sure there's a dependency problem with r-base-core. Running
sudo apt-install r-base-core r-recommended --simulate
gives the following output:

The following packages have unmet dependencies:
r-base-core : Depends: libc6 (>= 2.35) but 2.31-0ubuntu9.9 is to be installed
Depends: libicu70 (>= 70.1-1~) but it is not installable

libc6 2.35 or greater is required, but my system has 2.31 installed. According to a thread on this forum (Update "libc6" to version 2.34 or newer), updating libc6 isn't really an option. I really need to get this package working as soon as possible. How should I proceed?

That's a bit of a sticky situation, and it's been on-going for years.
Don't just install libc6 2.35 alongside 2.31... it'll crash your system, most likely. You have to change the path of 2.35 (put it somewhere else than default), then change the path in the R programming language so it references that 'somewhere else'. That's a lot of work, and you don't have to do it.
Do this instead... follow the directions here:
https://cloud.r-project.org/bin/linux/ubuntu/
Issue this command:
sudo add-apt-repository ppa:c2d4u.team/c2d4u4.0+
Then find the package for Focal Fossa (which is Linux 20.04, which Zorin OS currently uses). It should attempt to use libc6 2.31.
Alternatively, you can try using the Debian packages:

Thank you so much for responding. I've added the cran2deb repository and checked the launchpad page (cran2deb4ubuntu 4.0 : “cran2deb4ubuntu Build Team” team), but there are a few thousand packages listed and I'm not sure which one I need. From what I can tell most of them are libraries or addons for R
That gives me a similar dependency error:
$ sudo dpkg -i r-cran.deb
(Reading database ... 283710 files and directories currently installed.)
Preparing to unpack r-cran.deb ...
Unpacking r-cran-r6 (2.5.1-1cran1.2204.0) over (2.5.1-1cran1.2204.0) ...
dpkg: dependency problems prevent configuration of r-cran-r6:
r-cran-r6 depends on r-base-core; however:
Package r-base-core is not installed.
dpkg: error processing package r-cran-r6 (--install):
dependency problems - leaving unconfigured
Errors were encountered while processing:
r-cran-r6
That is strange... I installed that package to be sure it works before I posted the link.
Try:
sudo apt install r-base r-base-dev
Then re-run the .deb
I also install .deb packages with Gdebi.
apt install r-base r-base dev gives the same dependency error as in the original post
Let's see the terminal output of sudo apt update
Since we had different results- I wonder if you have added another repository.
It gives:

1 package can be upgraded. Run 'apt list --upgradable' to see it.
Here is your trouble. You have Bionic and Jammy sources added in addition to Focal.
These are different versions and they will call on different dependencies.
Please stick only with Focal (Fossa) repositories on Zorin OS 16.
Remove the two troublesome repositories either by using the Software & Updates app or by elevating to root and navigating to /etc/apt/sources.list.d directory to find and remove them.
You must keep the ppa.launchpad.net/c2d4u.team/c2d4u4.0+/ubuntu focal InRelease repository as it is correct.
Once done, run sudo apt update to get your sources updated to the existing repositories on your system. You might run sudo apt clean && sudo apt autoremove just to give yourself a bit more peace of mind.
$ ls /etc/apt/sources.list.d
bartbes-ubuntu-love-stable-focal.list easymodo-ubuntu-qimgv-focal.list.save zorinos-ubuntu-apps-focal.list zorinos-ubuntu-patches-focal.list.save
bartbes-ubuntu-love-stable-focal.list.save r-project.list zorinos-ubuntu-apps-focal.list.save zorinos-ubuntu-stable-focal.list
c2d4u_team-ubuntu-c2d4u4_0_-focal.list r-project.list.save zorinos-ubuntu-drivers-focal.list zorinos-ubuntu-stable-focal.list.save

easymodo-ubuntu-qimgv-focal.list zorin.list.save zorinos-ubuntu-patches-focal.list
There don't seem to separate repositories for bionic and jammy. Should I just remove r-project.list?
Yes, since you have c2d4u, that should be fine.
Ok, this is what my output looks like right now:

Ok, I was able to the r-cran package you recommended earlier after removing the other repositories, so I think the problem is solved!

Glad to hear. I went ahead and moved the Solution mark to @Mr_Magoo 's initial post due to that post containing the suggested solution - everything that followed just needed to straighten out repositories for that solution to work.
