I am trying to get my head around package managers. I recently installed llvm in macOS using
brew install llvm
I installed python3.8 using pyenv and CMake latest release from https://cmake.org/download/. Brew displayed this message after the installation:
==> Dependencies
Build: cmake ✘, python#3.8 ✘
Required: libffi ✔
I have 2 questions:
Should I be concerned that I did not install CMake nor python3.8 using brew? I would like to know before replacing my previous CMake and python3.8 installations with those offered by brew.
Is there a way to use pakages/software installed with brew and without it in the same project and not make everything a mess? If there is, how can I learn to do it?
I am a physics major so my knowledge in these topics is not as good as I would like to.
Thanks for the help!
I want to run ASP.NET MVC application in Debian 10 with Apache.
I have installed latest mono from mono Debian 10 repository using apt.
Trying to install mod_modo using
apt install libapache2-mod-mono
throws error

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

https://launchpad.net/ubuntu/zesty/amd64/nvidia-cuda-toolkit
above is the correct one.
apt-get install nvidia-cuda-toolkit
but remember the cuda installed through apt were installed in different location. manually create ln -s at /usr/local/cuda for include,lib64,and bin
I have successfully installed CUDA 8.0 + the latest patch from NVIDIA on Ubuntu 17.04:
Download the .run file from https://developer.nvidia.com/cuda-downloads, choosing Ubuntu 16.04 (Base Installer)
You will not be able to install it by just running, because it is looking for a file called InstallUtils.pm which is not present in Ubuntu 17.04, but curiously, is present in the .run file - so: unpack the .run file using ./cuda*.run --tar mxvf
copy InstallUtils.pm (should be in the /bin path) to /usr/lib/x86_64-linux-gnu/perl-base
Run the installer (You may want to say no to the driver install step to keep the one you install through apt - I'm using 381.22, because 375.26, which is provided by the .run file does not support my 1080ti)
gcc 6 is incompatible with CUDA, but this is easily remedied for compiling the sample files: just add export EXTRA_NVCCFLAGS="-Xcompiler -std=c++98" to your bashrc file, and comment out
from one of the headers (I think it was host_config.h, but you'll see it once you try to compile) - comment out these lines:
#if __GNUC__ > 5 || (__GNUC__ == 5 && __GNUC_MINOR__ > 3)
#error -- unsupported GNU version! gcc versions later than 5.3 are not supported!
This is all from memory, so hopefully it's accurate enough.
I managed to find this solution thanks to these useful posts:
https://devtalk.nvidia.com/default/topic/983777/can-t-locate-installutils-pm-in-inc/
https://devtalk.nvidia.com/default/topic/949770/cuda-8-0rc-supporting-gcc6-/
For ubuntu 17.04, I had to use cuda 9.0 (deb version)
https://developer.nvidia.com/cuda-release-candidate-download
I couldn't get it to work otherwise. Cuda 8.0 needs gcc 5.3.1 but cuda 9.0 is compatible with gcc 6.3.0 which is installed on ubuntu 17.04 automatically.
More precisely, this is what I did:
On Ubuntu 17.04, install CUDA 9.0 — you can currently download the beta version
https://developer.nvidia.com/cuda-release-candidate-download
I downloaded the .deb file and haven’t had any problems — follow the steps they recommend when you download cuda 9.0
sudo dpkg -i cuda-repo-ubuntu1704-9-0-local-rc_9.0.103-1_amd64.deb
sudo apt-key add /var/cuda-repo-9.0-local-rc/7fa2af80.pub
sudo apt-get update
sudo apt-get install cuda
Then follow the post installation steps from the nvidia instructions (i.e., setting PATH and LD_LIBRARY_PATH)
http://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html#post-installation-actions)
export PATH=/usr/local/cuda-9.0/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-9.0/lib64 ${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
Cuda 9 is compatible with gcc 6.3.0 (which comes with 17.04). I used arch=sm_52 and sometimes for my make files have to go ‘make clean’.
Installing Cuda 9.0 was the simplest solution in my case.
Alternatively, if you'd prefer cuda 8, you can download the deb file and then use the command
dpkg-deb -x cuda_8.*.deb /usr/local/cuda-8.0
to extract the contents from the deb file and have them placed in the desired directory.

I moved the question to the server fault site.
I want to install Apache with PHP 7.0 on Ubuntu 16.04 using Puppet Labs Apache module.
Following the documentation the module supports Ubuntu 16.04.
There is a ticket related with PHP 7.0 support and there is an accepted merge request which should add PHP 7.0 support.
It looks like the fix provided in the merge is not included in module 1.9.0 version.
The questions are
Is there any way how I can use the suggested fix and install Apache with PHP 7.0?
What should I write in the manifest?
The following code (from Puppet manifest) does not work on Ubuntu 16.04
class { 'apache':
mpm_module => 'prefork',
}
include apache::mod::php
I've got the following error
Error: Execution of '/usr/bin/apt-get -q -y -o DPkg::Options::=--force-confold install libapache2-mod-php5' returned 100: Reading package lists...

I tried to configure FastCGI servers to handle PHP files but this fails too with almost the same error message. The module knows nothing about PHP 7.0 yet.
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

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.

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.
