Modprobe command didn't present Ubuntu Server 18.04

#1

Hi Team,
Modprobe command didn’t present Ubuntu Server 18.04.
I checked with pc sever os this command is present but rock pi server os not available.
How to solve this issue ?
Why this command not present in ubuntu Server 18.04 os ?

Regards
Vasu

Hi igorp,
We are trying to attach 4G LTE module to ROCK PI 4 using USB interface.
We need to give vendor id and product id using modprobe command.
When i try sudo modprobe error is coming
bash - command not found
I check with /sbin/modprobe/ but this command didn’t present.
Not only modprobe insmod,rmmod commands also not present.
What was the issue rock pi ubuntu server os not supports modprobe (other kernel modules) commands ?

Hey my guy, try Armbian’s images (I’m using stretch, not buster) and see if that’ll work out for you instead… https://www.armbian.com/rock-pi-4/

https://dl.armbian.com/rockpi-4b/Debian_stretch_default.7z (<- this is the one that I use)

I tested ‘sudo modprobe -h’ on my current home debian stretch server, looks to be working just fine.

hi Kopono,

I tried to run modprobe on my board and got the desired result:

rock@rockpi:~ $ cat /etc/issue
Ubuntu 18.04.3 LTS \n \l
rock@rockpi:~ $ sudo modprobe -V
kmod version 24
-XZ -ZLIB -EXPERIMENTAL
rock@rockpi:~ $

Maybe you need to execute

sudo unminimize

Hi setq,
We got this response.

   rock@linux:~$ cat /etc/issue
   Ubuntu 18.04.3 LTS \n \l

   rock@linux:~$ sudo modprobe -V
   sudo: modprobe: command not found
   rock@linux:~$

What was the issue ?

#8

If i execute also there is no use.

#9

Broken image.

Use Armbian as already proposed. It 100% works.
