I just want to start by saying that my initial goal was to execute the following command:

$ sudo apt-get install build-essential cmake unzip pkg-config
But, then i received the following error:

enter code hereReading package lists... Done

Building dependency tree      

Reading state information... Done

build-essential is already the newest version (12.4ubuntu1).

pkg-config is already the newest version (0.29.1-0ubuntu2).

unzip is already the newest version (6.0-21ubuntu1).

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:

 cmake : Depends: libcurl4 (>= 7.16.2) but it is not going to be installed

E: Unable to correct problems, you have held broken packages.

Then, i followed the link :How do I resolve unmet dependencies after adding a PPA?, followed the steps there but I still couldn't succeed. The first problem I ran into was when running:

sudo apt-get upgrade

as, I got the following error:

Reading package lists... Done

Building dependency tree       

Reading state information... Done

Calculating upgrade... Done

The following packages have been kept back:

  r-cran-boot r-cran-codetools r-cran-spatial

0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.

Then , I tried removing them ( as i read in one of the threads) by using the command: sudo apt-get remove <packagename>
But I still couldn't fix it. This lead to another error as follows:

$sudo apt-get remove r-base-core

You'll have to tell us your version of Ubuntu; there are references to 16.04 LTS (xenial) in your messages, but the build-essential package you have is a 18.04 LTS (bionic) package (packages.ubuntu.com/search?keywords=build-essential). (packages.ubuntu.com/search?keywords=libcurl4)

On clean 18.04 LTS without any PPAs all mentioned packages may be installed without errors. Do you have any PPAs? Please add output of apt-cache policy r-base-core r-cran-boot to the question.

"You have requested an impossible situation" usually means that you have made unwise choices of the sources for your packages. It often means that you have added a source that provides wrong-release, wrong-version, or otherwise incompatible packages. Or if you have already removed the unwise source, you still have packages from that unwise source installed that must be removed.
