Evening,

I've attempted following the commands given here, but get the following error when running "sudo apt-get install openfoam6"

The following packages have unmet dependencies.
 openfoam6 : Depends: libopenmpi2 but it is not installable
             Depends: gnuplot-x11 but it is not going to be installed
             Recommends: paraviewopenfoam56 but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

If I just run "sudo apt-get install paraviewopenfoam56" or "sudo apt-get install gnuplot-x11" it appears to work, but obviously not super useful without the rest, when I try the other one I get:

Package libopenmpi2 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

E: Package 'libopenmpi2' has no installation candidate

I'm unsure why it's not installable - anyone got any suggestions?

Hello Lauren,

you need to install the dependencies first, you need to install libopenmpi-dev package!
try this:

sudo apt install libopenmpi-dev openmpi-bin

you may check the wiki for any other dependency in case of possible errors:

Even with the dependencies installed I get the same error, so I'm not sure sure it's that. I'll check the Wiki, cheers

Quick answer: A complete output of the command would have made it easier to diagnose the issue. Nonetheless, see possibility #3 at the Installation Problems section on the initial page you've referenced: https://openfoam.org/download/6-ubun...ation-problems

In other words, if the "universe" repository in apt is not active, then it's not possible to install certain packages that "openfoam6" depends on.
