[Solved] tmdb3 crashes

[marcw]

I've recently installed v31 as a standalone BE. (The database was restored from v28). It seems to be working well except I see a lot of tmdb3 crashes. Like daily. I'm not sure what tmdb3 does or even what it is except google tells me it's a python script that provides movie and TV info. Aside from the crash reports that land in /var/crash/ I can't find any logging or anything that would help troubleshoot this. I've looked for help in the wiki and either I'm blind or there's nothing there. Seeking ideas please, thanks!

tmdb3 is part of mythtv's metadata look up system which has just changed significantly see https://www.mythtv.org/wiki/Metadata_Lo ... March_2021

Please post the version of the OS and mythtv. In a terminal, run

Code: Select all

uname -a
mythbackend --version

In the mythtv backend log file (on ubuntu in /var/log/mythtv/mythbackend.log) you should see something like

Code: Select all

Running Grabber: /usr/share/mythtv/metadata/Movie/tmdb3.py -l en -a DE -C 24420

Please post the output of

Code: Select all

grep "Running Grabber" /var/log/mythtv/mythbackend.log

Change the path to the backend log file according to the log file location.

Additionally, the crash report does not contain any private data, so please zip one and attach it to this thread.

libmyth-python is not installed. I'll report back after installation and mythfilldatabase run.

[dnalorernst]

Either upgrade the mythtv installation to the latest installables and try to install libmyth-python,
or do an install of the libmyth-python package with the version required by mythtv-backend.

[marcw]

The BE seems to have launched tmdb3 successfully on its its own. Must be an internal scheduler. I noticed in the BE log that it seems to have grabbed data for a couple dozen TV shows so it must be working even though I'm not sure what it does with that data.
So it's clear now that the issue was caused by libmyth-python not being installed. I wonder why the installation routine of the backend didn't know enough to install libmyth-python on its own. I used the Mythbuntu Control Panel for the installation. Oh well. I'll mark this thread resolved.

[heyted]

I just checked mine with the backend installed using MCP with the PPA, and libmyth-python is installed. Not sure what happened in marcw's case.

[paulh]

libmyth-python is only a recommended package for mythtv-backend so wont be installed by default.

libmyth-python is a dependency of the mythtv-frontend package so will always be installed if the frontend is installed.
