E: Sub-process /usr/bin/dpkg returned an error code (1)
類似這樣的錯誤：
dpkg: error processing /var/cache/apt/archives/AAA (–unpack):
trying to overwrite `/usr/lib/BBB‘, which is also in package CCC
dpkg-deb: subprocess paste killed by signal (Broken pipe)
Errors were encountered while processing:
AAA
E: Sub-process /usr/bin/dpkg returned an error code (1)
解決方法：
sudo dpkg -i --force-overwrite AAA
(give full path of AAA), and then run
sudo apt-get -f install
again.
