Unpacking alsa-utils (1.1.8-2) ...
dpkg: error processing archive /tmp/apt-dpkg-install-y5aQgs/01-alsa-utils_1.1.8-2_arm64.deb (--unpack):
 trying to overwrite '/lib/udev/rules.d/90-alsa-restore.rules', which is also in package lxc-android 0.3+gemian+0~20210422170358.20~1.gbp8861de
dpkg-deb: error: paste subprocess was killed by signal (Broken pipe)

Fixed by force installing alsa with -o dpkg --force-overwrite
