Destroys the package dependency.

The package dependency-general Linux technology-Linux technology and application information is broken. The following is a detailed description. Another silly thing I 've done over the past few days is that I have broken down the package dependency of the Ubuntu system.

The cause of the incident was to install a software: Claws-Mail. Because the source code does not exist, a source code package is compiled. As a result, dependencies occur during the compilation process, indicating that a package is missing. I vaguely remember libetpan. I checked it and I have installed this package, however, the version is lower than the software requirement, so I want to update it. After apt-get update, the version has not been upgraded. So I went online with a new version of the libetpan package, the result is lack of dependency, a check, or version is too low, poor libetpan11-dev, so I went down another. Then there are a lot of dependencies like this, and I have issued a warning in the middle, saying that the dependency buffer (as if so) is damaged. Run sudo apt-get install-f to solve the problem, I tried it and found that he deleted many software packages based on the dependency, and even g ++ was deleted. At that time, I felt bad.

It's a pity that I continue to get confused. I basically changed all the software packages used for compilation, but it was also installed successfully. I found that the language of the software was changed to English, and it was useless to modify/etc/environment. I tried to restart it, and the result would fail to enter X. The Chinese character cannot be displayed, and I didn't translate it into English. I don't want to modify it. I'm very depressed. The dependency between software packages in the system has become a mess.
