The latest version of Ubuntu does not have VXLAN support.

Added package name

I tried updating the kernel but it defaults to 5.13.0-1008-raspi for both Ubuntu desktop and server versions

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1947628

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

>modprobe vxlan
modprobe: FATAL: Module vxlan not found in directory /lib/modules/5.13.0-1008-raspi

>updatedb
>locate vxlan.ko
/usr/lib/modules/5.11.0-1019-raspi/kernel/drivers/net/vxlan.ko
/usr/lib/modules/5.11.0-1019-raspi/kernel/net/openvswitch/vport-vxlan.ko

the vlan module (8021q) is also missing:
>modprobe 8021q
modprobe: FATAL: Module 8021q not found in directory /lib/modules/5.13.0-1008-raspi

>locate 8021q.ko
/usr/lib/modules/5.11.0-1019-raspi/kernel/net/8021q/8021q.ko
/usr/lib/modules/5.11.0-1019-raspi/kernel/net/dsa/tag_8021q.ko

temporary workaround until next kernel upgrade:
flash-kernel --force 5.11.0-1019-raspi

[Reinhard Tartler (siretart)]

This might actually be intended behavior. I noticed that 21.10 introduced a new package that contains the missing kernel modules in `linux-modules-extra-raspi`.

[Sundeep M (sjmach)]

Yes @siretart you are right. I added the extra package.

sudo apt install linux-modules-extra-raspi && reboot

Thank you everyone.
