Debian latest kernel 4.9.241 - no tun module

VIM3
1

Hi there!

I have been using debian image for khadas vim3 for over the year and today updated kernel to 4.9.241 and suddenly my tailscale client won’t start.
The reason is that there is no tun module in kernel!?!?

modprobe tun returns this → Module tun not found in directory /lib/modules/4.9.241

Any chance to enable module in kernel config and build kernel again?
I see it is commented # CONFIG_TUN is not set

Best regards,
Sinisa

I found this problem too (/dev/net/tun not found).
I set CONFIG_TUN=y and recompile kernel 4.9, It’s work.

Yes I know maybe @numbqq can enable it again. I have created pull request on github :wink:

Okay, merged, thanks for your PR. :grinning:

Great! Thanks.

When will new kernel image be ready to download?

Best regards,

Hello @ssehovic

For Ubuntu focal image you can upgrade the kernel to fix this issue.

sudo apt update
sudo apt full-upgrade
sync
sudo reboot

Hi @numbqq,

and what about Debian? Is it the same?

Just to inform you I have this error:

Until it is fixed I have found this “fix”.

The debian package is zst compressed and debian buster doesn’t support it.

I have rebuilt the packages, you can install under Debian Buster.

cd /tmp
wget https://dl.khadas.com/.test/1.3.1/linux-dtb-amlogic-4.9_1.3.1_arm64.deb
wget https://dl.khadas.com/.test/1.3.1/linux-image-amlogic-4.9_1.3.1_arm64.deb
wget https://dl.khadas.com/.test/1.3.1/linux-headers-amlogic-4.9_1.3.1_arm64.deb
sudo dpkg -i *.deb
sync
sudo reboot

Hi @numbqq,

is there a way to upgrade existing debian buster to debian bullseye on vim3?

Best regards,
S.

@ssehovic It seems infeasible.

Hi @numbqq,

I just created a simple shell script to repack deb package.
So if anyone stumble on this “zst” problem a simple script is here.
Repack script
