I installed latest fresh new Ubuntu on my laptop and installed KStars from the Software section. I tried to start the Simulators profile in EKOS but getting the above attached error. I'm not able to find the log location as each button to open the logs does not open the log folder. I would highly appreciate for any help in resolving this error.
Never mind... I uninstalled and re-installed KStars as per the below link from Jasem's repo and this error did not get reproduced... Many thanks to everyone if they spent any time to read about the issue...
