EV3 not working after OpenRoberta upgrade #26

Closed JimZam closed 7 years ago

JimZam commented 7 years ago

Good morning. After the last OpenRoberta update all I get is a white screen when trying to run any program from the openroberta web or offline server. I can access via ssh. Thank you and regards

Server update or local package update? If you can ssh in, then this could help: https://github.com/OpenRoberta/robertalab-ev3dev#logging Put the last few lines on a gist.github.com and share it here, if that is okay with you.

I upgraded openrobertalab in the EV3, will post the status this evening (I'm in Spain :-) ) Thank you

JimZam commented 7 years ago

Ok, it seems to work now. Something to do with the existing NEPOprog.py file:

Nov 27 16:52:50 ev3dev openrobertalab[386]: PermissionError: [Errno 13] Permission denied: '/home/robot/NEPOprog.py'

I deleted it, ran the program from the web browser and everything was fine.

By the way, if I try to run "python NEPOprog.py" from the command line it keeps on failing (it seems it would be solved in this update according to my last question)

robot@ev3dev:/home/robot# python NEPOprog.py Traceback (most recent call last): File "NEPOprog.py", line 3, in from roberta.ev3 import Hal ImportError: No module named roberta.ev3

Thank you so much for your help and for OpenRoberta

Not being able to run the programs from the brick (e.g. the file browser) is fixed with the new release - when upgrading from python2 to python3, I forgot to update the first line in the script :/ The stored programs unfortunately will only work for as long as the python libraries don't change in an incompatible way.

I'll check what happens if a program cannot be overwritten and how I can gracefully handle this.

ensonic commented 7 years ago

I am already catching the error, but only logging it. The program would run, but not be stored. I don't see a good way of solving this though. At some point I can report back to the server that the program already existed and could not be overwritten (see #20).
