Ran these commands. sudo apt install cmake git clone https://github.com/rkaczorek/astroberry-diy.git Now need to do a bit of editing to remove unwanted drivers from Radek's Astroberry set as per my Tutorial page Installing 3rd Party Drivers.

Done. Onwards and upwards... ?

Waiting for backup to finish...

To close down the RPi safely use :- sudo shutdown -h now

sudo shutdown -h now Safely shuts the RPi down.

Tried again with Ubuntu Mate 16.04 and it all worked.

Think I'll save an image of the SD card before continuing. I think there's a Linux app but forget what so I'll use my Win7 laptop and Win32 Disk Imager.

It works!! ? Next is to load the Astroberry drivers, install my modifications, compile and install drivers. ATM I only have the camera driver operational. Here's a screenshot or two from the KStars FITS Viewer - camera sitting on a box in my living room.

Phew!! I need a break now.

Rebooted but now the GUI is not working - just showing four raspberries. However, the WiFi is working and I have been able to SSH into the RPi from Mint. A new IP address was allocated to the ASC so had to follow the instructions to clear the old allocation. gina@Mint-Desktop ~ $ ssh gina@asc @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: POSSIBLE DNS SPOOFING DETECTED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ The ECDSA host key for asc has changed, and the key for the corresponding IP address 192.168.1.249 is unknown.

Script finished and ready for rebooting. At this point I can test it with the camera then go on to install my own focuser driver alterations.

Voila!!! It's all working - including the script

Restarted the system and the CPU activity was low so tried the command again in Terminal and it worked Now to try the rest...

Only difference closing Firefox made was to reduce memory useage. Something is exercising the CPU and at quite a high rate. Screenshot of System Monitor without Firefox running.

It's definitely doing something. Firefox is running - maybe it's that. I'll close Firefox and see what gives.

MATE System Monitor shows PulseAudio and itself running only. Processor is active though.

Now getting a problem earlier on!!

Yes, that's what I think too. BTW - Now in Ubuntu Mate on RPi connected via WiFi and Firefox is running fine now. I'll try the script but as you say, doubt it will work and it so I'll comment out the dpkg check.

I can email him and also he used to be available on the INDI forum where I'm a member. Meanwhile, I've written Ubuntu Mate 16.04 to the card and will try that.

Yes, I think so.

Hmm... the date on the script file is 2018 so it may be that I used an earlier version of the script. Since the system is new and there should be nothing running when I try to run the script, I see no reason to check dpkg but Robert Lancaster (the author) knows much more about these things than me.

That script has worked before with Ubuntu Mate 16.04, assuming the script hasn't changed. I'll check that (if I can).

Seems to me the easiest option would be to go for the previous version of Ubuntu Mate and start over as there are several things wrong with the way the current system works.

After a quick check to see if we're ready, the script starts off with a test of dpkg and the error message is coming from the script. Script file is HERE This is the relevant section :- ## check if DPKG database is locked dpkg -i /dev/zero 2>/dev/null if [ "$?" -eq 2 ] then echo "dpkg is currently locked, meaning another program is either checking for updates or is currently updating the system." echo "Please wait for a few minutes or quit the other process and run this script again. Exiting now." exit fi
