Christian, when you say "update your system" can you be more specific. Here's my problem....
I am starting from Stellarmate OS version 1.7.3 - Stable - SM-110 installed on the Pi (this is the 64 bit version). I have already updated the Android app to version 2.5.8. I have tried updating the OS repeatedly but each time it fails or does not seem to update.
Method 1 - Direct
I have the Raspberry Pi attached to a monitor , keyboard, mouse and connected to my home network. I click on the icon "Stellarmate Tools" on the desktop. It confirms that I am on version 1.7.3 Stable. I click the "Check for updates" button, and I get the message an update is available and is being installed. The progress bar climbs to around 78% in about 15-20 minutes then tells me to reboot. So I reboot.
Results vary.... On two occasions the Pi refuses to reboot - I assume because something was corrupted during update. On one occasion, the OS starts up but the icons for Kstars, PHD2 are clearly broken and when I click on them, an error message pops up that the source file cannot be found - so another broken update I guess. So I click on Stellarmate tools again and the window confirms that I am still on version 1.7.3. I click on the update button thinking that the update didn't take but I am told there is no internet connection (but I am connected to my network) After each failure I re-flash the SD card and re-install the OS.
Method 2 - via the Android App
After reflashing my SD card back to version 1.7.3 ....again, I connect from the Android app (running version 2.5.
, I go to the device tab in the Android app where I see 1.7.3 is confirmed). I change the connection to my network and I am informed an update is available. So I click on it and it appears that an update is being installed. Many minutes later I reboot the system and I have the same problem where the Pi will not reboot. On one occasion it does, but the device tab in the android app screen still reports I am on version 1.7.3 - i.e. no update occurred.
I also tried the same method but leaving the build selector on "Stable" but same problem occurred.
After two hours of very annoying frustration and re-flashing the SD card multiple times, I was ready to quit Stellarmate and order an ASI Air. So frustrating that such a simple update cannot be performed without errors (I owe Bill Gates an apology for the number of times I cursed Microsoft but that is a breeze compared to this cludge. There is another topic here recently about "How to update Stellarmate" and it seems I am not the only frustrated user.
Since the only reliable way I can update the system seems to be via a full re-flash of the SD card, is there somewhere I can download the "Fixed" version?
As I have stated I am new to the world of Fruit Pi's so if I am doing something wrong, would someone please take me by the hand and walk me through it because for the life of me, I have no idea what I might be doing wrong.
