Using distrobuilder in ubuntu_latest on aarch64 will give an error( Failed to unshare namespaces: Operation not permitted )

Very nice program.
But I'm having some minor problems with it.

https://github.com/oneclickvirt/incus_images/blob/main/.github/workflows/build_kali_arm64.yml

I tried to compile and install https://github.com/lxc/distrobuilder for use using the ubuntu_latest image on the aarch64 architecture, but it reported an error during use $HOME/goprojects/bin/distrobuilder --version:

Failed to unshare namespaces: Operation not permitted

        cd $HOME/go/src/github.com/lxc/
        git clone https://github.com/lxc/distrobuilder
        cd ./distrobuilder
        make
        export PATH=$HOME/goprojects/bin/distrobuilder:$PATH
        echo $PATH
        find $HOME -name distrobuilder -type f 2>/dev/null
        distrobuilder --version
        $HOME/goprojects/bin/distrobuilder --version

So far I've only done the above, Is there any way to perform the repair?

According to https://unix.stackexchange.com/questions/669523/why-non-root-user-cannot-unshare-pid-namespace the unshare (pid) namespace operation needs CAP_SYS_ADMIN capability, i.e. root access to the host.
You may try to add --cap-add SYS_ADMIN to the action's dockerRunArgs but I barely remember that Github Actions forbids this.

I add --cap-add SYS_ADMIN and got another error Failed to mark / private: Permission denied.
There seems to be no solution to this problem.
