Unable to install AverMedia A835b USB TV tuner in Ubuntu 22.04 container on Proxmox

[issa2020]

Hello everyone,

I have recently installed an Ubuntu 22.04 container on my Proxmox server and installed the TVHeadend application. Now, I am trying to install my AverMedia A835b USB TV tuner by following the steps below:

Prerequisites:

sudo apt-get install wscan

wget http://www.ite.com.tw/uploads/firmware/v3.6.0.0/dvb-usb-it9135.zip

unzip dvb-usb-it9135.zip

rm dvb-usb-it9135.zip

dd if=dvb-usb-it9135.fw ibs=1 skip=64 count=8128 of=dvb-usb-it9135-01.fw

dd if=dvb-usb-it9135.fw ibs=1 skip=12866 count=5817 of=dvb-usb-it9135-02.fw

rm dvb-usb-it9135.fw

sudo mv dvb-usb-it9135* /lib/firmware/

However, I am encountering the following error message within the container:

root@tvheadned:~# sudo mv dvb-usb-it9135* /lib/firmware/

mv: target '/lib/firmware/' is not a directory

It seems that the /lib/firmware/ directory does not exist in the container. Can anyone help me understand why this directory is missing and how I can resolve this issue?
how to use my usb keys on the container please

Thank you in advance for your help.

Containers share the Linux kernel with the Proxmox host. Therefore any drives (and firmware) need to be loaded on the Proxmox host.
You probably want to put the firmware file on the host and bind mount the /dev/dvb directory to the container (like lxc.mount.entry: /dev/dvb dev/dvb none bind,create=dir 0 0) and setup all the necessary users/group mappings. There are several threads about this on this forum.
If you don't want the firmware and drivers on the Proxmox host, or you want hot-plug/unplug of the USB tuner to work: use a VM and USB passthrough or PCIe passthrough of a USB controller.
