[SABnzbd3] nice: can't execute '/var/packages/sabnzbd/target/var/scripts/Deobfuscate.py': No such file,but file is there

Since the upgrade to SABnzbd my scripts are not working anymore.
The error:
nice: can't execute '/var/packages/sabnzbd/target/var/scripts/Deobfuscate.py': No such file or directory
But the file is there:
# ls -al /var/packages/sabnzbd/target/var/scripts/Deobfuscate.py
-rwxrwxrwx 1 sc-sabnzbd sabnzbd 7872 Aug 24 15:29 /var/packages/sabnzbd/target/var/scripts/Deobfuscate.py
#
In the previous version this worked (at least: I did not get errors). I also tried /volume1/@appstore as path, but wanted tot test it without the @-sign.
I have a simular issue for CharTranslator.py
What is going wrong?

The
No such file or directory part could also be referring to whatever is in the shebang line inside the script, for example an outdated or otherwise incorrect path to a python interpreter.

The chartranslator was removed from the Synology package because it was not python3 compatible.
Maybe the nice command is the problem. Could you try with nice disabled? (remove the nice parameters to disable it)

When disabling nice I get:
Exit(-1) Cannot run script /var/packages/sabnzbd/target/var/scripts/Deobfuscate.py
When starting it manually it does not end in an error (immediately):
# python3 /var/packages/sabnzbd/target/var/scripts/Deobfuscate.py
This script needs to be called from SABnzbd as post-processing script.

so (like jcfp said) ... what are the first lines of /var/packages/sabnzbd/target/var/scripts/Deobfuscate.py ?

The error "Cannot run script" is one thrown by SABnzbd. In the Debug logging it will specify the actual exception that was thrown. Could you check that?

The first lines. Is this sufficient?

Deobfuscation post-processing script:
Will check in the completed job folder if maybe there are par2 files,
for example "rename.par2", and use those to rename the files.
If there is no "rename.par2" available, it will rename the largest
file to the job-name in the queue.
Can I mail the debug? I don't want to put it here.

Yes,

You could try to remove the first line, then SABnzbd should default to just putting "python" in front of it.

I mailed.
But ... when I remove the first line, it works as expected. Thats nice! :-)

I checked and the Synology Python is located in:
/usr/local/python3

What is preferred: adding it to to first line, or just leave it out? Fow now it works.

Maybe should add a detection that checks if the part after the shebang even exists? What do you think Sander?

Yes, we can do that for scripts SAB tries to run (pre-queue, post-proc), if on POSIX.
If path-to-executable not correct ... clear warning / error message? Or overrule the shebang with by calling "/real/path/python3 <thescript.py>"? And discover /real/path/python3 by using the python-path that was used to start SABnzb itself?
We earlier discussed putting "#!/usr/bin/env python3 " as first line in scripts (the solution I like; let the OS handle it), but you (@saifhre) showed that that can cause other problems.

So my initial guess was right.
Best to leave it at /usr/bin/python3, which works in most cases. If the script comes as part of a package (don't have synology stuff around to try but the path /var/packages/sabnzbd/target/var/scripts/Deobfuscate.py does suggests so) and the system uses non-standard locations for interpreters, its maintainer should adjust any shebang lines accordingly.

Well, I am the maintainer of the Synology package.. So guess I have work to do
