Dear All Fluka users,
I need your help regarding an error while I was going through the Fluka wsl set-up.
When the server was trying to connect to the fluka website I received the following error:
--2021-01-04 07:45:37--

### - Download of FLUKA failed
### - No FLUKA package available, try again later

Can you help me out?
Thanks

Hello
Fedora 33 has a strict policy for SSL versions.
The real solution will be to update the fluka website. This will come in the future.
For the moment:
Chrome works, it is enough to accept the connection when asked.
For firefox the workaround is to give, once for ever, from the command line:
update-crypto-policies --set DEFAULT:FEDORA32
This has to be issued from the root use. Otherwise, from a user with
root privileges:
sudo update-crypto-policies --set DEFAULT:FEDORA32
restart firefox afterwards.
Hope this helps
Happy new year to you and all fluka users
Paola
