How to fix Python ValueError:bad marshal data?

Question

Running flexget Python script in Ubuntu, I get an error:

$ flexget series forget \"Orange is the new black\" s03e01
Traceback (most recent call last):
File \         


        

Answer 1

If you get that error, the compiled version of the Python module (the .pyc file) is corrupt probably. Gentoo Linux provides python-updater, but in Debian the easier way to fix: just delete the .pyc file. If you don't know the pyc, just delete all of them (as root):

find /usr -name '*.pyc' -delete
