Errors running setup on WSL

Hi Fluka experts

I am trying to setup Fluka/Flair again. After my windows PC was updated to 21H2 it seemed to stop working.
When I run the setup script I now get the errors as below.


$ sudo ./

Updating package list …
E: Failed to fetch 403 Forbidden [IP: 443]
E: The repository ‘ InRelease’ is not signed.
W: Target Packages (Packages) is configured multiple times in /etc/apt/sources.list:50 and /etc/apt/sources.list:52
W: Target Translations (en) is configured multiple times in /etc/apt/sources.list:50 and /etc/apt/sources.list:52
[ERROR] Couldn’t update pacakge list. Try again later.

Dear Michael,

it seems there was / is a temporary issue accessing the repository. Could you try it again later?

If you are still getting strange errors, you may try to reset your WSL, and reinstall Fluka and Flair completely.

If the problem is persistent, you could download the appropriate .deb packages, and install Flair manually.

Finally, I would suggest to use Ubuntu 20.04 LTS, because Ubuntu 22.04 LTS has been released a few days ago, so it is likely that the support for Ubuntu 18.04 LTS will be dropped.


Thanks David

I installed it on Ubuntu 20.04 and all seemed to work OK.
