I need to install this driver to make my DVB-T USB dongle work. I used this tutorial https://rk.edu.pl/pl/obsluga-tunerow-dvb-t-pod-linuksem/ Here is what I did:

git clone git://linuxtv.org/media_build.git
cd media_build

Then I run command ./build. When I do this, I get several errors:

libkmod: ERROR ../libkmod/libkmod-module.c:1668 kmod_module_new_from_loaded: could not open /proc/modules: No such file or directory
Error: could not get list of modules: No such file or directory

Preparing to compile for kernel version 5.4.163

File not found: /lib/modules/5.4.163-17364-gfe3d4f499cf1/build/.config at ./scripts/make_kconfig.pl line 33,  line 4.make: *** [Makefile:367: allyesconfig] Error 2
make: Leaving directory '/home/tabsik12/media_build/v4l'
make: *** [Makefile:26: allyesconfig] Error 2
can't select all drivers at ./build line 531

How can I fix this? I have little knowledge about Linux on Chrome OS.

I have 2K(2560x1440 16:9) monitor, i have Firefox extension (Netflix 1080p) for the name of science and for my interest i want to watch Netflix in 4K, please tell me is it possible to watch Netflix with 4K quality ? And how this service checks our devices for 4K supporting and we able to imitate what our device supports 4K ?

Please, help I have a TV tuner on Windows, there are no problems with it - all frequencies are found and shown, but in Linux it cannot find all frequencies ( https://linuxtv.org/wiki/index.php/Astrometa_DVB-T2 with Sony CXD2837ER finds from 722000 frequencies to 778000, but from 786000 to 858000 writes - no signal DVB-С or tell me please where to write? I've never run into problems on Linux so I don't know where to write and where to create tickets. i try write email to media-workshop@linuxtv.org, pkg-vdr-dvb-devel@lists.alioth.debian.org but there was no answer (

Done, scan time: 09:07.744

dvb-fe-tool is able to list some device capabilities and delivery systems, but it does not seem to list the supported codecs by the hardware. I'd like to know if my tuner supports MPEG4 hardware decoding or not without looking for the chip specs on the web.

**libdvbv5** has no option for KU-CIRCULAR LNB frequency (10750,10750,0), how to solve this? in the Ubuntu Yakkety Yak libdvbv5 are used as a back end for kaffeine 2.0, and in the kaffeine 2.0 program, doesn't exist any option for LNB with the parameters: high 10750, low 10750, swith 0 i.e. for so-called ku-circular standard of Russia satellite tv. I don't know, how to create a patch for libdvbv5, to solve this problem. I only found [this patch](https://www.mail-archive.com/kde-bugs-dist@kde.org/msg119521.html) but that isn't what i need.

I'm trying to use w_scan to scan the transponders from a satellite, on Debian 8.0 it worked, but on Debian 8.7 it doesn't work. At the same time, i can scan all the transponders by using Kaffeine (Version 1.2.2). I.e. all is almost good, but I really need to get w_scan to work as well. How to solve the problem? sudo w_scan -t2 -l 10750,10750,0 -o21 -fs -sS36E0 -v -v **Log:**
