When I type
sudo apt-get install r-base-core
I get the following error
The following packages have unmet dependencies.
r-base-core : Depends: libc6 (>= 2.29) but 2.27-3ubuntu1 is to be installed
Now libc6 as far as I understand is an important library which should not be removed.
So how to upgrade from the current version (2.27) to any version >= 2.29?
Here is Solutions:

So anyone who is trying this, please be careful and make sure you create backups before trying it.
To my knowledge, libc6 2.29 is the latest version. And it is available for Ubuntu 19.04 (link).
If you want to install libc6 amd64, open this link to download it, then open the download folder in the terminal and run
sudo dpkg -i libc6_2.29-0ubuntu2_amd64.deb
If you want to install libc6 i386, you can download it from this link, then open the download folder in the terminal and run
sudo dpkg -i libc6_2.29-0ubuntu2_i386.deb
As per now, libc6_2.29 does not exist anymore. However libc6_2.30 and lib6_2.31 are available via this [link] (2.31 is the official version for Ubuntu 20.04).
If you want to download a different version than the official one supported by your Ubuntu release (i.e 2.27 for 18.04, 2.30 for Ubuntu 19.10 …), check [this link] Download the version that suits you, then open the download folder and run `sudo dpkg -i `.
Don’t do it. Here I’ll leave an image of how dependent are your software packages on
libc6 compiled for that specific library!!! https://sites.google.com/view/dependency-netwok/.
There you’ll see a star shaped network and the node at the center (green colored) represents
libc6. I suggest two possible solutions to your problem:
1. Add a compatible repository
Since it is r-base-core what you want, change the repository to a compatible one for your specific distribution.
deb https://cloud.r-project.org/bin/linux/ubuntu bionic-cran35/
In your /etc/apt/sources.list file. By using you will be automatically be redirected to a nearby CRAN mirror. See https://cran.r-project.org/mirrors.html for the current list of CRAN mirrors.
sudo apt-get update sudo apt-get install r-base sudo apt-get install r-recommended
Another solution would be to upgrade your entire distribution to a more recent and compatible with what you want.
Note: Use and implement solution 1 because this method fully tested our system.
Thank you 🙂
