After days of travelling without internet - today I changed HDD on my computer. I both copied /home and reinstalled the system partition / to a new and larger drive.
So the system is new.
I also did update and upgrade.
I then ran the installer of Beta6 and again: no entry in the start menue (I had to create this manually).
After doing that RPD starts fine.
The app itself is beautiful - thanks.
I’ll have another look in the translations.
Btw: When starting from the command line I get
$ ~/.local/bin/rapid-photo-downloader
You are using pip version 8.1.1, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
Is this a message of RPD?
