Unpacking firmware-misc-nonfree (20161130-5~deb8u1) ...
dpkg: error processing archive /var/cache/apt/archives/firmware-misc-nonfree_20161130-5~deb8u1_all.deb (--unpack): trying to overwrite '/lib/firmware/kaweth/trigger_code.bin', which is also in package linux-firmware-image 16.04.05

竟然...沒包好，兩個 package 有相同的 install file。所以衝突。

follow 這一篇，force-overwrite...

#sudo dpkg -i --force-overwrite /var/cache/apt/archives/firmware-misc-nonfree_20161130-5~deb8u1_all.deb

這樣就 OK 了..

只有等待mantainer 在下一版會修正。
