OSMOSDR source_c creation failure in op25

[FrostWizard4]

I am fully aware of THIS post and i have followed it multiple times, however whenever i reinstall op25 with ./install.sh i get the same error over and over again:

osmosdr source_c creation failure
Traceback (most recent call last):
  File "./rx.py", line 921, in <module>
    rx = rx_main()
  File "./rx.py", line 835, in __init__
    self.tb = p25_rx_block(self.options)
  File "./rx.py", line 123, in __init__
    gain_names = self.src.get_gain_names()
AttributeError: 'NoneType' object has no attribute 'get_gain_names'

should i just wipe linux?
(Im using windows 10 as my primary driver but i have a separate partition for linux with ~ 30 GB)

No wipe, we need to find out what's going on otherwise it will keep happening.

Start with the RTL dongle unplugged, execute a "dmesg" command, save the output, plug in the dongle and then re-run the same dmesg command. The additional information which appears the second time should relate to the kernel detecting and loading drivers for the rtl device.

With the dongle plugged in, execute a 'lsusb' command and see ifL device is recognized.

Assuming the device is appearing in the lsusb listing, chances are it needs to be blacklisted properly. Post the debug info from above and we'll see where to go next.

 

[FrostWizard4]

here are all 3 files saved from the terminal output,
help is dmesg without RTL-SDR
helpsdr is with RTL-SDR
lsusb is, lsusb obviously.

 

[FrostWizard4]

Also i was setting up op25 for my friend and everything worked correctly in the same setup

 

[boatbod]

The RTL device is being recognized by the kernel, so the probability is that it's not blacklisted correctly.

As superuser, make a text file named /etc/modprobe.d/blacklist-rtl.conf

blacklist dvb_usb_rtl28xxu
blacklist rtl2832
blacklist rtl2830
blacklist rtl2838

If you already have a file in that location with a similar name, make sure it has the same contents as above.
Reboot and try op25 again.

 

[FrostWizard4]

I opened the file and found exactly what you put,

blacklist dvb_usb_rtl28xxu
blacklist rtl2832
blacklist rtl2830
blacklist rtl2838

 

[FrostWizard4]

I also used rm to remove op25, reinstalled and got the same error
When i setup op25 on my friends RaspPi he needed 198 updates but it worked
I think the updates made your code fail.

 

[boatbod]

What happens if you run the command "osmocom_fft"?

Please report output of:

apt list --installed | grep rtl
apt list --installed | grep osmo

How about:
apt list --installed | grep swig

Why does it keeps saying the warning?

Why does it keeps saying the warning?

I used the same command boatbod mentioned and I got the same results you had.

swig:

Looks like APT isn't well used in scripts. Reference apt gives “Unstable CLI Interface” warning

I wouldn't worry about it. My copy of OP25 installed fine. (after 200000000 attempts before I switched to a more Debian based distro).

 

[FrostWizard4]

The only problem now is the source_c creation failure.
Thanks for the clarification!

 

[FrostWizard4]

Any other commands I should put in boatbod?

 

[boatbod]

Sorry for the delay in responding.

The curious thing is that your rtl driver appears to be installed and the dongle is correctly blacklisted in the kernel. The swig package is installed, but you are getting errors when you try to start either osmocom_fft or rx.py. Can you re-run rx.py and post the command line you used along with the complete log for it trying to start. I'd also be interested in whatever text has appeared on the terminal window when rx.py exits.
