Because I have not using Arch Linux, but an Arch Linux based distro (Manjaron).
Thanks, now I understand those commands. The other commands had got really rare syntax for me.
Ok, now the connection with missions servers work fine and I can start downloaded missions correctly. However I have got new issue. I try to explaining here but say me if I must to open a new thread.
Now when I go to missions section, it apparently is not show anything but... check it for your own:
There are three "invisible" missions preinstaled that are "Training mission", "newjob" and "stlucia". For some reasons I can't see names from the list but I can select them, download them and play them. What could be the reason?
