Bazarr: Bazarr does not start after update

[pven]

I just got a warning telling me to restart Bazarr to apply the last update. After this, Bazarr does not start anymore. I am running at a Synology.

When I start it at the prompt, I see:

Bazarr starting...

What can I do to get it starting?

I suppose you are running from source and not inside a docker container? Are you using some kind of package to install Bazarr?

[pven]

Yes, I am running from source. Docker is not working at my Synology. I downloaded it from github, and run it using Python. I had problems before, they were solved after installing Python Modules on my Synology.

[morpheus65535]

You didn't specify your Python version. The issue template for bugs include questions that need to be answered to help us in debug process. This isn't optional.

[pven]

Sorry, here it is

Describe the bug
When starting Bazarr after applying the last update, it won't start. See the log above.

Expected behavior
Start ;-)

Software (please complete the following information):

• Bazarr: I've changed it back to 0.7.0.5, so it is a version above that
• OS: Synology, newest DSM
• Python: 2.7.12

Additional context
Just let me know if I missed some information, and I will provide it.

[morpheus65535]

Try to update python. Version 2.7.13 is minimal requirement.

[pven]

I have no idea yet how to update Python on my DSM. But it has my attention.

[morpheus65535]

No clue either. Good luck! ;-)

[pven]

When I succeeded in updating I will re-open this issue, when needed. Thx!

[pven]

I mailed with Synology support. They are not going to update Python2, since I probably installed it by a custom package. However: they do support Python3.

Is Bazarr supported on Python3? Last time I tried it with Python3 it failed.

[pven]

'version 3.x not supported'

Hm, that sucks. :-) Any idea if this is on the list somewhere?

[pven]

In the meanwhile I traced the error to this line in libs/scandir.py

        libc = ctypes.CDLL(ctypes.util.find_library('c'), use_errno=True)

[morpheus65535]

Can you try the dev branch?

[pven]

I just tried, I get exactly the same error.

Let me focus on the python-upgrade. However I have the feeling that somehow that won't solve the problem with the missing library.

[morpheus65535]

Have you seen this post?

[pven]

Yes

I just also found out that setting a variable works !!! :-)

export PY_CTYPES_LIBPATH=/usr/lib/python2.7/ctypes

Damn, so easy. But hard to find...

Thanks for all the support on this issue!

[morpheus65535]

Thanks for reporting! I hope it will help other users! :-)

[pven]

Just to mention: I was able to install the last update without any problems. It looks solved for good. :-)
