Hi Juan,
No things different more than the typical linux instalation updates.
I download it again and I can confirm that any image to be integrated give the same error. Just the preference icon in Image Integration tool gives the crash. See a new video in endor.
I am opening Pix from the bin folder by double click in PixInsight.sh and running Image Integration previously to any change, even the updates.
However, if I use slot #2 it works, so I seems that there should be something to be reset in slot#1, but I do not know how to do that, and i have already re-instaled PixInsight.
In the mean time the workaround solve the problem but if you have any idea to reset slot #1 would be great.
