在Ubuntu 11.10的opencv安裝

Question

我想在Ubuntu11.10上使用終端安裝OpenCV。但它給了我以下錯誤。我一直無法解決它。注意最後四行。

對於這樣的錯誤：

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) 

（其中AAA，BBB，CCC是佔位符名稱，如果它是不明確）

做

sudo dpkg -i --force-overwrite AAA 

（給出AAA的完整路徑），然後運行

sudo apt-get -f install 

再次。
