Question

我正在尝试使用终端在Ubuntu11.10上安装OpenCV。但它给了我以下错误。我无法解决它。注意最后四行。

Answer 1

对于这样的错误：

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是占位符名称，如果不清楚的话）

DO

sudo dpkg -i --force-overwrite AAA

（给出AAA的完整路径），然后运行

sudo apt-get -f install

试。

此外，在发布问题之前尝试谷歌搜索，因为有大量链接解释如何解决此错误！
