我正在尝试按照此处的说明安装 OpenCV4：https ://www.learnopencv.com/install-opencv-4-on-ubuntu-16-04/
当我到达
sudo apt -y install libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev
我收到

我在网上查了一下，这些包可以在https://packages.ubuntu.com/search?keywords=libgstreamer0.10-dev 找到
我尝试手动下载和安装
sudo apt install ./libgstreamer0.10-dev_0.10.36-1.5ubuntu1_amd64.deb
这给了我
Note, selecting 'libgstreamer0.10-dev' instead of './libgstreamer0.10-dev_0.10.36-1.5ubuntu1_amd64.deb'
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:

Depends: libxml2-dev but it is not installable
Depends: gir1.2-gstreamer-0.10 (= 0.10.36-1.5ubuntu1) but it is not installable
E: Unable to correct problems, you have held broken packages.
我是 Ubuntu 的新手（只使用过 Manjaro）。我不明白为什么 apt 无法找到网站上的包裹。

libgstreamer0.10-dev 在 Ubuntu 18.04 中已过时。
因此，请改用较新的版本：
sudo apt install -y libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev
这肯定会奏效。
