HiPS gone after update was created by Peter Sütterlin

Hi,

I know that's a kstars question, not EKOS/INDI, but I hope I can also get some feedback.
My HiPS overlay is suddenly gone. I only get the option 'None'. I'm not sure what triggered it. I had installed the latest version of kstars git, and also updated my system. And I'm sure I used DSS color overlay yesterday.
I don't see an error message regarding this in the logs - any idea where I could start looking for the cause?
This s****, just wanted to start looking for targets for tonight....

Update - that seems to be an issue in the sqlite database. I saw this in the logs:

so I moved the userdb.sqlite away, now HiPS is back - but my whole EKOS config is gone. :(
Are there any tools to fix that thing?

Looks like the file got corrupted somehow. This is not an update issue since the update doesn't install or changes this file. Maybe some issue with the file system?

Hi Jasem,

thanks! Yes, I figured that out. Still unfortunate. Is there a way to properly backup the configuration? Should it be enough to just copy the sqlite file (when kstars is not running)? I guess in my case it didn't help because it already had been bad...

I had a crash of kstars this morning when trying some stuff, likely that one corrupted the file.

Fortunately although I had to create new profiles for EKOS, the main settings of everything were still fine, so I'm currently running again :D
Still scratching my head which configuration parts are stored where. Guess I need to RTFM more often...

Yes, I think you should make a backup of your most important configuration files just in case something happens. Sometimes if I am working on something that I know will change my settings (which I will want back to my settings later)l, I will copy my config files somewhere else, then do what I want to do, then copy the files back again.

Well this is an odd coincidence -- I am also unable to see HIPS overlays all of a sudden, and I have also had a major system re-arrangement today.

My Ekos profiles look fine, but when I View HIPS overlays, all I get are weird bands of horizontal blotches that look like smeared out stars. Looks like old analog TV static.

All is well when I turn off the HIPS displays.

I have reinstalled KStars, but the corrupted static still appears with any and all HIPS overlays.

Is there a file or directory I can delete someplace and re-download the HIPS imagery?

Indeed intriguing....
I did have issues with the display, too. Especially also with my local horizon (I had defined one). Things *seem* much smoother now.
The HiPS stuff is downloaded and cached IIRC. Maybe that one is also organized in that database? At least that was the only file I moved away. So you could try that (move ~/.local/share/kstars/userdb.sqlite away to start it from scratch)
Then again, you might better not follow my suggestions after what I did to my setup :o
But as I understand the advice from rlancaste you can just back up/copy those files and restore them later.

Yes put those files you care about in a VERY safe place while you play with things and experiment. I have accidentally misplaced them before. . .

I've seen similar corruptions, too.

But I was refering to a local horizon to map obstructions. That worked fine in Alt-Az display mode, but in Ra-Dec the polygon would be drawn distorted all over the sky.
I lost the horizon definition during my crash, I first have to recreate it to further investigate and/or show examples...
