How to install mod_mono on Debian 10 ?
/etc/apache2/mods-available contans mod_mono.
Maybe it is sufficient to enable it in apache to get it work ?
/etc/sources.list contains:
deb http://ftp.debian.org/debian buster main contrib non-free
deb http://ftp.debian.org/debian buster-updates main contrib non-free
deb http://security.debian.org buster/updates main contrib non-free
/etc/apt/sources.list.d contains two files:
mono-official-stable-list:
deb https://download.mono-project.com/repo/debian stable-buster main
and pgdg.list:
deb http://apt.postgresql.org/pub/repos/apt/ buster-pgdg main
#deb-src http://apt.postgresql.org/pub/repos/apt/ buster-pgdg main
Update
I tried commands from GAD3R answer.
apt install libapache2-mod-mono
still fails. Error message is a bit different:
Hit:1 http://security.debian.org buster/updates InRelease
Hit:2 http://ftp.debian.org/debian buster InRelease
Hit:3 http://ftp.debian.org/debian buster-updates InRelease
Hit:4 http://apt.postgresql.org/pub/repos/apt buster-pgdg InRelease

The files that are required to do development on top of a package are often separate (since this is really only needed by developers, and would take up too much size for no reason otherwise).
In your case, the package you're looking for is libbluetooth-dev. So you can do sudo apt install libbluetooth-dev
Hi i am trying to install Apache2 server on my Ubuntu 12.04, but when i enter this command sudo apt-get install apache2 i am getting this error -
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:

How do i fix this problem??
I found answer while installing add apache2-bin dependency to do that follow this command :-
sudo apt-get install install apache2 apache2-bin
Recently reinstalled my computer with Ubuntu 14.04.
This pc is to be used to develop ASP.NET mono applications.
So I installed the latest 3.12.0 version of Mono.
Also installed Apache2 (2.4.7 is the latest).
Last thing is to install Mod_Mono. This is where it fails.
sudo apt-get install libapache2-mod-mono

The following packages have unmet dependencies:
libapache2-mod-mono : Depends: apache2.2-common but it is not installable
E: Unable to correct problems, you have held broken packages.
So I tried to install apache2.2-common but that does not exist, there is only a apache2.2-bin. I installed that and it still did not solve my problem.
sudo apt-get install apache2.2-common
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package apache2.2-common is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
apache2-bin:i386 apache2:i386 apache2-data apache2-bin apache2
E: Package 'apache2.2-common' has no installation candidate
Any suggestions to what I can do so I can host my Mono application through apache2?
Solved this issue by installing Apache 2.2.22.
Had a bit of trouble doing that, but finally installed it running this command.
sudo apt-get install apache2=2.2.22-1ubuntu1.7 apache2.2-common=2.2.22-1ubuntu1.7 apache2.2-bin=2.2.22-1ubuntu1.7 apache2-mpm-worker=2.2.22-1ubuntu1.7
Note: you need to add the precise repository to your software sources, else you won't have the package available to install.
I have tried to install mod_security, but it has the error, so I tried aptitude:

**Keep the following packages at their current version:**

2) libapache2-modsecurity [Not Installed]
3) modsecurity-crs [Not Installed]
Accept this solution? [Y/n/q/?] q
Abandoning all efforts to resolve these dependencies.
I do now know what Keep the following packages at their current version means.
I want to know what does happen if I press yes. Does it replace my current apache2? Do I need to back up before doing this?
ANSWERS
I do now know what Keep the following packages at their current version mean
aptitude is trying to resolve the dependencies and possible conflicts to satisfy your installation request. It then proposes a solution. In your particular case the first solution it finds is to keep everything as it actually is, that's what keep at their current version + [Not installed] means.
I want to know what does happen if I press yes , does it replace my current apache2 ?
No, that solution will basically do nothing.
Do I need back up before ?
As boring as it sounds, backups are a good strategy to save time in the long run. If you're messing with important data then it should be even more important for you.
CONTEXT
I've seen other scenarios make aptitute propose solutions with combinations like these:
Remove the following packages
Keep the following packages at their current version
Leave the following dependencies unresolved
The following packages have been kept back
The following packages will be upgraded
The following packages were automatically installed and are no longer required
The following extra packages will be installed
Suggested packages
The following packages will be REMOVED
(and probably others)
In your case if instead of accepting the solution (or quitting), you reject it by pressing n, then aptitude will try to figure out another scenario that could be useful and propose it to you again. You can iterate through the solutions doing that and if any of them satisfies you then you can accept it.
SOLUTION (?)
As far as I can see by your output:
apache2.2-common : Depends: apache2.2-bin (= 2.2.22-1ubuntu1.4) but 2.4.6-2~precise+1 is installed.
Your problem is that you have apache2-2.4.6-2~precise+1 installed which isn't available from standard Ubuntu precise repositories (most probably installed from this PPA), and you're requesting a package which conflicts with that other one.
I'd take a look at the answers on how to remove PPAs and after you have removed that source I'd reinstall apache 2.2 from the standard repos with this command:
sudo aptitude install apache2
That's exactly what it did for me:
$ sudo apt-get remove apache2-bin
$ sudo apt-get autoremove
$ sudo apt-get install apache2
Open synaptic manager and search for apache2.2-bin. Mark it for removal. Then
sudo apt-get install apache2
Just remove all the content of /var/lib/apt/lists directory:
sudo rm -rf /var/lib/apt/lists/*
then run:
sudo apt-get update
