Installation of the driver for the TBS 5927 fails

[VDelport]

Hello,
I tried to install the driver for the TBS 5927 receiver using the following command:

sudo blocksat-cli deps tbs-drivers

I get the following error message:

/home/delport/.blocksat/src/tbsdriver/media_build/v4l/ccs-core.c: In function 'ccs_set_ctrl':

Hello @VDelport ,

Could you share the Linux distribution and kernel version you are using? Is that also on Linux Mint? Kernel 6.8.0? Could you please share the result of the following commands?

uname -a

and

cat /etc/os-release

or

lsb_release -a

Hello, is there any solution to the problem?

[blockstreamsatellite]

Hello, @VDelport .

Yes, this is a known issue with this kernel version. The following command should fix it:

blocksat-cli deps tbs-drivers --backport-disable v6.8-ccs.patch

[VDelport]

After installing the driver I get the following error message:

blocksat-gui
2025-02-05 16:32:25 WARNING Could not find the dvbnet interface name. Is the TBS 5927 receiver running?
2025-02-05 16:32:25 WARNING Assuming interface name dvb0_0.

This seems to be a permission issue. Try adding your user to the video group with the following command:

sudo usermod -a -G video $LOGNAME

[VDelport]

sudo usermod -a -G video $LOGNAME
does not lead to a solution:

blocksat-gui
2025-02-06 10:39:39 WARNING Could not find the dvbnet interface name. Is the TBS 5927 receiver running?

2025-02-06 10:39:39 WARNING Assuming interface name dvb0_0.
dmesg: Reading kernel buffer failed: operation not permitted
2025-02-06 10:39:40 ERROR No DVB-S2 adapters found

blocksat-cli --cfg CFG usb ls
2025-02-06 15:03:19 INFO Find DVB adapter
2025-02-06 15:03:19 ERROR No DVB-S2 adapters found

Obviously no interface dvb0_0 is created.
What commands can be used to create this interface without having to use blocksat-cli?

[blockstreamsatellite]

First, please note that the usermod -a -G video command does not take effect immediately in the terminal session. You would need to log out and back in for it to take effect. Alternatively, you could run the following command to apply the group in the current session:

newgrp video

Second, there is a chance your kernel got updated without you noticing, in which case you would have lost the TBS drivers and would need to reinstall them. Run uname -r again. Do you still have kernel 6.8.0-51-generic? Maybe it got updated to 6.8.0-52-generic while rebooting. See if that is the case.

If you lost the TBS drivers, the following command would not return anything:

lsmod | grep dvb

On the other hand, if the drivers are still there, and you have the TBS receiver connected, you would see something like:

dvb_usb_tbs5520se      20480  0
dvb_usb                45056  1 dvb_usb_tbs5520se
dvb_core              184320  1 dvb_usb
rc_core                73728  1 dvb_usb
videobuf2_vmalloc      20480  1 dvb_core
videobuf2_common       90112  3 videobuf2_vmalloc,dvb_core,videobuf2_memops
mc                     81920  3 si2157,dvb_core,videobuf2_common

The above is for the TBS5520SE but should be similar for the TBS5927.

If that is all confirmed, go ahead and reinstall the drivers:

blocksat-cli deps tbs-drivers --backport-disable v6.8-ccs.patch

Once the drivers are reinstalled, you can check the lsmod | grep dvb command above or run blocksat-cli usb list to see the device listed. Alternatively, you can check the dmesg logs with the following command:

sudo dmesg | grep dvb

If you would like to prevent this issue from happening again (kernel updating on reboot), you can configure it to be held with a command like the following:

sudo apt-mark hold linux-image-$(uname -r)

Lastly, for your question:

What commands can be used to create this interface without having to use blocksat-cli?

You can run the USB configuration in dry-run mode to see the commands that are executed:

blocksat-cli usb cfg --dry

[VDelport]

Maybe it got updated to 6.8.0-52-generic while rebooting. See if that is the case.

Yes, it is the case.

lsmod | grep dvb returns nothing.

And now?

[VDelport]

Hello,
I have now found the solution to the problem.
I had to disable secure boot.
