The service cant find amdfan - Debian 11

[MatiasPujado]

Big Thanks

Hi! Thank you so much for keeping the project alive, I found it really useful specially combined with conky.

The Issue

I'm facing a weird situation. I'll explain: I've installed amdfan using this command: sudo pip3 install amdfan. Then I started setting it up exactly how is detailed in the Readme file and by the time I was done I got this error when I ran sudo systemctl status amdfan:

● amdfan.service - amdfan controller
     Loaded: loaded (/etc/systemd/system/amdfan.service; enabled; vendor preset: enabled)
     Active: failed (Result: exit-code) since Tue 2022-02-15 21:43:52 -03; 24min ago
    Process: 179413 ExecStart=/usr/bin/amdfan --daemon (code=exited, status=203/EXEC)
   Main PID: 179413 (code=exited, status=203/EXEC)
        CPU: 649us

So I went to check on both of the files I created. Here is what I have: cat /etc/amdfan.yml

#Fan Control Matrix.
# [<Temp in C>,<Fanspeed in %>]
speed_matrix:
- [4, 4]
- [30, 33]
- [45, 50]
- [60, 66]
- [65, 69]
- [70, 75]
- [75, 89]
- [80, 100]

# Current Min supported value is 4 due to driver bug
#
# Optional configuration options
#
# Allows for some leeway +/- temp, as to not constantly change fan speed
# threshold: 4
#
# Frequency will change how often we probe for the temp
# frequency: 5
#
# While frequency and threshold are optional, I highly recommend finding
# settings that work for you. I've included the defaults I use above.
#
# cards:
# can be any card returned from `ls /sys/class/drm | grep "^card[[:digit:]]$"`
# - card0

and cat /usr/lib/systemd/system/amdfan.service

and that's when I took a closer look with sudo journalctl -u amdfan:

So it seems that the service can not find the binary. I checked and it is not there: ls -alh /usr/bin | grep amdfan And I cant find it, but! look at this output: amdfan --monitor

Aborted!

So... is it running?It is clear that the OS was able to identify it and allow me to run it manually, my guess is that was installed in another directory. I'll update if I find anything new. I'd appreciate if anyone could point me in the right direction. Its an amazing software and I would love to get it running properly. Thank you in advance

which amdfan should tell you where the binary is that you were able to call as your user, then you can probably use that.

The /usr/bin link is only created when installing from the AUR in arch linux.

Thank you Jason! I copied the binary to the /usr/bin directory and it got fixed!
