Cannot load credentials

[pswiatki]

Installed pw-sat2-gs on Arch Linux using pikaur (helper for pacman allowing it to work with AUR). All went well, I could launch the app without any problems. However, when trying to load my (newly generated) credentials.json - I got this error

Further inspection of the console output (where I launched the app from) reveals this:

2018-11-25 13:57:22,083 DEBUG: [app.load_credentials_file] Selected file: /home/pswiatki/Downloads/credentials.json
2018-11-25 13:57:22,083 DEBUG: [app.load_credentials_file] File valid
2018-11-25 13:57:22,083 DEBUG: [app.load_credentials_file] Load file exception
2018-11-25 13:57:22,085 DEBUG: [app.gui_pyqt.StartQT4] Not updated credential file - wrong or empty path

Seems that everything that got installed in /opt/pw-sat2-gs has write permission only for root. I suspect that whatever is read from credentials.json is supposed to be stored somewhere /opt/pw-sat2-gs and that fails for non-root user. To prove the point - when chown is used on the app's installation in /opt/pw-sat2-gs credentials get loaded nicely.

Wouldn't it be good to store credentials on a per-user basis?

You're right that that the app assumes write permissions for it's installation directory. It was created to be just 'portable' app, so I assumed that you unzip it in the directory with sufficient permissions (read/write) for normal user. The distribution for Arch (AUR package) was created by the community. Our fault is that we didn't tested it extensively to avoid such problems... The only thing that I can do for now is to mention this issue and fix/solution next to AUR package or remove the package from the wiki since it introduces some 'mess' for users.

Please, mention that the additional step (making installation writable for the intended user) is needed, but do not remove from the WIKI. Perhaps there are other users who use Arch Linux who would be interested in your project and would participate, especially during flight. Cannot wait until I can properly decode some real time frames!
