The videos don't download and nothing is reported as an error #2434

We git-hubbed the ka-lite on newly installed ubuntu 14.04. It worked until we tried to download videos. The webpage at 127.0.0.1:8008 reported the video download started but nothing happened next few minutes and no error was reported. On another system (Ubuntu 12.04 freshly installed) the same procedure worked and videos were downloaded correctly.

I'd love to add any concrete bug reports but I don't know how to make ka-lite print it's debug on console or somewhere else.

aronasorman commented 10 years ago

Strange. Did you try redownloading the videos again on the faulty system?

aronasorman commented 10 years ago

Can you run echo "DEBUG = True" > local_settings.py inside your ka-lite/kalite directory and see if it would give more meaningful errors?

LechMankiewicz commented 10 years ago

Aron, I am an idiot, but if I type 'echo "DEBUG = True" > local_settings.py' inside ka-lite directory and press enter it just copies DEBUG = True to the local_settings.py file. If I subsequently run ka-lite it writes something on screen...

Hi @LechMankiewicz, can you try reproducing @ChewbaccaKL's bug with DEBUG turned on?

LechMankiewicz commented 10 years ago

@ChewbaccaKL did it on my laptop. I do not know how to turn DEBUG on...

aronasorman commented 10 years ago

Hi Lech,

It was already turned on with the echo DEBUG = True line given above.

LechMankiewicz commented 10 years ago

OK, so the problem with downloading videos persisted, and I copied above everything which appeared on screen

aronasorman commented 10 years ago

Is there no output from the terminal after triggering the download? There should be some new output. Can you paste them here?

LechMankiewicz commented 10 years ago

The problem is that it says nothing more.

aronasorman commented 10 years ago

Can you try manually running python manage.py videodownload --commandline and see if there's any output?

LechMankiewicz commented 10 years ago

can't open file 'manage.py': [Errno 2] No such file or directory Indeed, there is only file local_settings.py, just opened by the 'echo' command

aronasorman commented 10 years ago

ah, make sure you're inside the ka-lite/kalite directory.

Resolved on hipchat. Turns out to be related to the psutil issue.
