Resolve dependencies for mobilemediaconverter and monodevelop

Question

I recently installed a video converter software and later I removed it.

After removing it, I can't seem to install any other software. It seems when I removed the video converter software, it also removed some library that is necessary for other software to be installed, too.

Now, I want to install monodevelop, but it again notifies so much dependencies!

Here is what my terminal says:

$ sudo apt-get install monodevelop

You might want to run 'apt-get -f install' to correct these:

E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Please, can you give me any solution to the problem.

Have you done: apt-get -f install ? – George Udosen Apr 23 '17 at 12:39 — George Udosen, Apr 23 '17 at 12:39

If you read the output from apt it says:

...Building dependency tree       
Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:......
E: Unmet dependencies. Try 'apt-get -f install' with no packages

From man apt-get:

   -f, --fix-broken
       Fix; attempt to correct a system with broken dependencies in place.
       This option, when used with install/remove, can omit any packages
       to permit APT to deduce a likely solution. If packages are
       specified, these have to completely correct the problem. The option
       is sometimes necessary when running APT for the first time; APT
       itself does not allow broken package dependencies to exist on a
       system. It is possible that a system's dependency structure can be
       so corrupt as to require manual intervention (which usually means
       using dpkg --remove to eliminate some of the offending packages).
       Use of this option together with -m may produce an error in some
       situations. Configuration Item: APT::Get::Fix-Broken.

After that, I can suggest you try:

sudo apt-get build-dep monodevelop

Apt will search for all dependencies related to monodevelop.

After that,

sudo apt-get install monodevelop

Ultimately, you can check everything you're looking for with

sudo apt search packagename

To search repositories for packagename.

sudo apt show packagename

To show detailed description of the packagename.

You can simulate the apt-get process by using

sudo apt-get -s install packagename

and

sudo apt-get -s build-dep packagename

From man apt-get:

-s, --simulate, --just-print, --dry-run, --recon, --no-act
       No action; perform a simulation of events that would occur based on
       the current system state but do not actually change the system.
       Locking will be disabled (Debug::NoLocking) so the system state
       could change while apt-get is running. Simulations can also be
       executed by non-root users which might not have read access to all
       apt configuration distorting the simulation. A notice expressing
       this warning is also shown by default for non-root users
       (APT::Get::Show-User-Simulation-Note). Configuration Item:
       APT::Get::Simulate.

"Now, I want to install monodevelop, but it again notifies so much dependencies!"

Dependencies are usually a must, but sometimes can be omitted when they are referred to as Recommends.

From man apt-get

   --no-install-recommends
       Do not consider recommended packages as a dependency for
       installing. Configuration Item: APT::Install-Recommends.

Generally, it is good to build-dep then install package.

Get in the habit of using the man pages.

From shell type:

man command

and read.

thanks , I used this "apt-get -f install" as it is a duplicate question.. but thanks for the response — FerdousTheWebCoder, Apr 24 '17 at 08:17
