Linux Client 2.5.24 not installing urbackupclient_dmsnaptool for debian arm64

On a new Linux Debian arm64 Client I’ve just installed 2.5.24, with dm snapshotting.
Which failes snapshotting and as usually just start filling up the harddisk with the overlay files.
If the binary doesn’t exist for arm 64, it shouldn’t allow to choose dm-snapshots during installation.

Edit: the installer detects aarch64-linux-android as architecture
