I am having issues using the vlan package on Ubuntu Server installed on a Raspberry Pi 4. I am running Ubuntu 21.10.

I will run the command sudo apt install vlan and the package will download. When I run sudo modprobe 8021q I am getting this error

modprobe: FATAL: Module 8021q not found in directory /lib/modules/5.13.0-1015-raspi

I have done research on this error and have not found anything that has helped. How can I resolve this error?

You need to install the package linux-modules-extra-raspi:

sudo apt install linux-modules-extra-raspi

The 21.10 release notes briefly call out that some kernel modules have been moved to this package (including apparently 8021q).

Try to (re)generate module dependency list and check modprobe once again. Whole installation sequence is:

sudo apt-get install vlan 
lsmod | grep 8021q
grep 8021q /etc/modules
sudo echo "8021q" >> /etc/modules
sudo modprobe 8021q
grep 8021q /etc/modules

Possible way how to fix missing modules:

sudo apt install --reinstall linux-image-5.13.0-1015-raspi

Check directory content of: /lib/modules/

/lib/modules/5.13.0-1015-raspi

/lib/modules/5.13.0-1015-raspi/kernel/net
