Python ssl issues with lastgenre

Help
1

I am a newbie to beets and it seems amazing however I am having problems getting it configured and working properly.
The last piece to get working is lastgenre I am getting a certificate error with it
Hardware: Synology NAS DS1511+
OS: DSM 6
beets version 1.4.3
Python version 2.7.13
plugins: acousticbrainz, beatport, chroma, discogs, fetchart, lastgenre, lyrics, missing

command : beet -v lastgenre gives
error : lastgenre: last.fm error: NetworkError: [SSL: CERTIFICATE_VERIFY_FAILED] unknown error (_ssl.c:661)
lastgenre: last.fm error: NetworkError: [SSL: CERTIFICATE_VERIFY_FAILED] unknown error (_ssl.c:661)

I think its a synology/python error, seems to be to do with #PEP 493: “private” API to configure HTTPS defaults without monkey patching

but I have no idea how to fix it, can anyone help?

Hmm, that’s odd… I’m assuming this has to do with the version of Python provided by Synology. This thread seems to reflect the same problem, for example: https://forum.synology.com/enu/viewtopic.php?t=98648

Perhaps the solution is to try installing Python manually, or to switch to a different version of Python (e.g., 3.6)?

Thanks for the response! So I took your advice and removed 2.7.13 (also had to remove a bunch of other packages including beets before I could remove python) these are the steps I took

  1. opkg remove --force-removal-of-dependent-packages python
  2. Ran opkg install python3
  3. Had to reinstall pip - wget https://bootstrap.pypa.io/get-pip.py
  4. python3 get-pip.py
  5. pip install beets
    It seemed to install ok and seems to be using python 3.6 here is the output

Had to obviously reinstall all the plugins I had which again seem to switch over to python 3.6 as this shows

But I have exactly the same output if I run beet -v lastgenre

Is there any way I can check what version is actually running?

Actually just checking it the line number is now different so I guess its using 3.6
lastgenre: last.fm error: NetworkError: [SSL: CERTIFICATE_VERIFY_FAILED] unknown error (_ssl.c:749)
lastgenre: last.fm error: NetworkError: [SSL: CERTIFICATE_VERIFY_FAILED] unknown error (_ssl.c:749)

Any ideas?

Huh! That’s very strange. My best guess at this point is that your system didn’t come with a full battery of SSL certificates, or they’re not installed properly. This comment on another project’s similar issue with the Synology OS: https://github.com/SynoCommunity/spksrc/issues/1575#issuecomment-84695701

seems to indicate it might be possibly by linking the certificates into the right place. Maybe try that, or a little more googling about certificates on Synology in general?

Thanks sooooooo much for your help and pointing me in the right directions
After much googling and not finding much at all I began messing about and seeing what I could find.

Some trial and error and I came across this which worked just grand!
opkg install ca-certificates

just in case anyone else has this issue

Nice! Good to know it was just missing certificates.
