Hi everyone,



I'm trying to learn OpenFoam and i'm having some troubles trying to install the software. Here is what the terminal is giving me back after i run the command "sudo apt-get install openfoam7"


Here is the message:
"Err:1 https://jztkft.dl.sourceforge.net/pr...am/foam/ubuntu focal/main amd64 openfoam7 amd64 20200508

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?"


I'm really interested in learning the software so I really appreciate if anyone could help me around this problem.

Could try following these instructions and see if you have better luck

Thanks for the reply!


Unfortunately, I've been trying with that and many other basic and simple installation guides but nothing seem to be working, this is the last mistake i got when i try to run the "add-debian-repo.sh" script.

It looks like you missed out the "sudo" part of the instructions. Even if you download it to a file location, you need root permissions to add the gpg keys and setup the repo locations. That's what the sudo is for.

Not quite, that was the latest error that i got after applying all the other commands, if i follow the normal installation procedure this is what i get.

Any update on this? I am having similar problems.

[MisterChuy]

I typed following command at terminal prompt
(my installation is for Ubuntu 20 on Windows 10 subsytem for Linux

sudo apt install ca-certificates

my problem was with supposedly expired certificates of sourceforge.net so I was not able to create repository so system could not be installed

Hope it helps
