Bootstrap problem - FIXED

[hstox]

Hi,

I'm experiencing the same problem as John White mentioned on the tvheadend forum, but as no solution was given there, let me repeat it here:

configparser object doesn't use defaults and first getitem raises a key error. AFAIK I initialized all directories and permissions correctly. I'm running it on an apache2 on an RPI4, using Python 3.9.2 for cgi. Any ideas on how to bootstrap from scratch?

Thanks in advance.

From the python_errors dump:

Traceback (most recent call last):
File "/usr/lib/cgi-bin/tvh_epg.py", line 1691, in <module>

I am trying to bootstrap by requesting [hostname]/cgi-bin/tvh_epg.py, and this results in a 500 internal server error, because the included python error may not contain html comments in the page header output, so I need to retrieve the error from the logs, instead of seeing it in my browser.

Hi,
ensure the user id which runs the web server has a directory it can access.

root@mcintyre:~# cd /var/lib/tvh_epg/
root@mcintyre:/var/lib/tvh_epg# ls -la
total 12
drwxrwsr-x  2 root www-data 4096 May 15  2022 .
drwxr-xr-x 56 root root     4096 May 15  2022 ..
-rw-rw-r--  1 root www-data  567 Dec 10 19:45 tvh_epg_settings.ini

in theory you should be able to go into the settings page and save an initial settings file, if not, here's what it would look like. if you need to create this file manually, let me know, and I'll try setting my tvh epg up from scratch, I've not done it in a long time, so it is possible that I need to fix this process up.

# cat tvh_epg_settings.ini

Hi, thanks for your quick response. Changing the owner of the config dir back to root didn't help for me, but the template settings file allowed me to bootstrap, and now I am able to navigate the EPG. (will try Chromecast and/or local playback later.)

thanks for letting me know.

I will go through the bootstrap process from scratch to identify why the script doesn't correctly tell you what is wrong and how to fix it.

Hello,
I found and fixed the problem. the script always ran the function to generate the html header, which used values from the global settings, and of course if the settings hadn't loaded then it would error. now, if there's no settings file, or it didn't load, it will go to the settings page and the html header generator doesn't care so much if the settings isn't loaded.
