Greetings! Iḿ new to Raspberry Pi and new to GPredict. I loaded GPredict 1.3, because thatś all that showed up with the Raspbian ¨Add or Remove Software¨ feature. There are no ground tracks showing up for any satellites. I updated the TLEs, but still no ground tracks. I tried upgrading to GPredict 2.0 and 2.2, but I keep failing due to ¨permission denied¨. I have nearly zero Linux experience, so I don´t know how to work around this. Hopefully it is just an option in the software that I failed to set, but I am hoping someone can provide a solution. Everything is new: Raspberry Pi 3B and latest Raspbian. Any advice? I did a search of the forum but turned up nothing. Thanks in advance!
