Cannot run program "docker" (in directory ...

[lhehjvgtycsd]

Hi,

I've installed openFOAM v1606+ and HELYX-OS v2.4.0 per the installation process "Installation of the Latest 64 Bit Linux Binaries" on the github page. HELYX opens up fine but when I come to generate a mesh I get 'Cannot run program "docker" (in directory ...

See attached screenshot.

Any ideas?

Did you try apt-get update && apt-get install docker ?
Also make sure that your user is in the docker group: sudo gpasswd -a $USER docker

Many thanks for your help! Unfortunately neither of the above worked. I should point out that I'm not a Linux expert so when you see the cut-and-paste from my terminal window you will see that $USER appears. After this I realised this was probably supposed to be my username - but that didn't work either.

Have you got any other ideas?

The first command must also be run as root so do sudo apt-get update && sudo apt-get install docker
The second command, try sudo usermod -a -G docker $USER

Still no luck I'm afraid! See output from terminal below ...

x@x:$ sudo usermod -a -G docker $x
[sudo] password for x:
usermod: group 'docker' does not exist
x@x:$

Did the first install command work?
If not then its clear the group docker does not exist yet.

Here's what I get when I run the two commands - apologies for not coming up with useful suggestions but Linux is new to me!

Ok, then check whether ubuntu is maybe using a different and auto-configured group (docker needs to be installed, as it seems you did it just before) name for docker by doing grep -i docker /etc/group if that is completely empty, do sudo groupadd docker. If it was not empty, use the previously posted command to add your user to the posted group.

You know, I'm wondering if OpenFOAM is actually installed on my box? In the GitHub installation instructions for HELYX-OS there is a step where it says it will automatically install OpenFOAM along with HELYX-OS and this was the option I selected but I'm not sure it worked. I can't find any folders relating to openfoam OR docker. That is just by searching from the Ubuntu file manager - perhaps there is a smarter way. What are the default locations for openfoam and docker so I can check to see if they are actually there?
