License checkout failed.
License Manager Error -9
The hostid of your computer ("00155de21a38 6a0b4012aaac") does not match the hostid of the license
file (00155db048ba).

Hi, Chenguang Wan.

It is possible to use MATLAB inside WSL2, the problem is that everytime you open WSL2 its MAC Address changes! And your license is linked to it.

The solution is edit ".bash_profile" and add a few lines. On Linux, type:

$ nano ~/.bash_profile

Then insert these lines:

wantmac=00:15:aa:ad:aa:aa
mac=$(ip link show bond0 | awk '/ether/ {print $2}')
if [[ $mac !=  $wantmac ]]; then
    sudo ip link set dev bond0 address $wantmac
fi

Now you just need to activate your MATLAB again and it will work!
