[BUG] unable to import smbus

[dga4130-renato]

Rpi 4
libreelec 12

Argon Fan script not working after upgrading from LE11 to LE12.
debugging the argon script says:

unable to import smbus and fails the startup service.

Traceback (most recent call last):
File "argononed.py", line 4, in
import smbus

Fan starts and never stops.

Reverting to LE11 all working fine.

Confirm the system-tools addon is installed and enabled on LE12.

I'm closing this ticket becuase LE does not provide/ship any Argon case-fan scripts in our images, so if there's a bug, it's the responsibiliy of the script author to investigate and resolve it, not ours. NB: ISTR there's a thread in the forum where someone is working on a proper Argon case add-on to support their features.

It's the system-tools addon bug.
If you login ssh and call python up
Then import smbus you will see python loaded but smbus missing even if the smbus.so lib is there.

Maybe same bug

System-tools installed but smbus module not working

@heitbaum this looks related to work on #7602 If I add PYTHONPATH=/storage/.kodi/addons/virtual.system-tools/lib.private when calling python, it's able to import smbus.

ah, good catch, the python stuff shouldn't have gone to lib.private but remained in lib (libi2c can stay in lib.private, rpath of smbus.so needs to be adjusted to $ORIGIN/../lib.private)

Should be a quick fix done in system-tools ?
If could help I can test it fast...

[heitbaum]

Just testing the fix

Just testing the fix

Safe to install ? i mean if upgrade to le12 this fix will be present now ?

[antonlacon]

Wait for tomorrow. Builders and mirrors need to get the changes.
