I have installed version 8.0 on my linux computer, running ubuntu release 18.04. I have installed and reinstalled several times now but I get the same problems.
When SNAP opens I get the ‘unable to install colour palettes’ error.
I use SNAP to analyze S2-MSI images but I cannot open products from .xml Nothing happens when I try this.
I can open .nc files generated by ACOLITE.
I just tried supervised classification using maximum likelihood and also got an error.
Or you don’t have write access to the .snap directory in your user_home for some other reason.
At least the message that colour palettes could not be installed sounds like this.
