Debian

apt commands

To search for package

apt-cache search gcc

See a description of package

apt-cache show gcc

Install a package

sudo apt install gcc

Remove a package

sudo apt remove openmpi-bin

Setting the locale

If the locale is not set correctly, you can get weird errors while installing some softwares. Edit the file /etc/locale.gen with this line

en_US.UTF-8 UTF-8

and run sudo locale-gen command in the terminal.

Install packages

I use Spack to install scientific packages. Before that, install some needed dependencies

sudo apt install gcc g++ gfortran gnuplot make curl wget git vim

Next see the Spack tips for installing other softwares. openmpi will also be installed by Spack, so do not install it from apt.
