Today, I will talk to you about how to solve the error report when installing ImageMagick in the Ubuntu system. Many people may not know much about it. In order to make you understand better, the editor has summarized the following contents for you. I hope you can get something according to this article.

Find a problem

When trying to install ImageMagick using apt-get install, there was a problem of missing dependencies:

The following packages have unmet dependencies

After updating the index and upgrading all packages using the apt-get update, apt-get upgrade commands, it still cannot be installed. Again, using the apt-get install-f command to fix dependencies still has no effect.

Solution process

So use aptitude to install, and found that there is no aptitude on the command line, so you can only install aptitude through the apt-get install aptitude command, and then encounter the problem of lack of dependency:

The following packages have unmet dependencies Depends: libstdc++6 (> = 4.9) but 4.8.4-2ubuntu1~14.04 is to be installed

An attempt was made to install libstdc++6 using apt-get install and could not be installed successfully. So manually download the deb package of libstdc++6 to install:

$apt-get download libstdc++6$ sudo dpkg-I libstdc++6_4.9.2-10ubuntu13_amd64.deb

Get an error prompt:

Dpkg: dependency problems prevent configuration of libstdc++6:amd64: libstdc++6:amd64 depends on gcc-4.9-base (= 4.9.2-10ubuntu13), however: Version of gcc-4.9-base:amd64 on system is 4.9.3-0ubuntu4.

Solution method

This is because the version of gcc in my Ubuntu is 4.9.2-0ubuntu4, while libstdc++6 relies on the version 4.9.2-10ubuntu13.

Therefore, the dependent version of gcc-4.9-base is installed through apt-get install gcc-4.9-base=4.9.2-10ubuntu13.

Then, execute the above command to install libstdc++6

After that, use apt-get install to install aptitude

Finally, use aptitude to install ImageMagick

Finally installed ImageMagick, summed up the problems encountered in the installation process: mainly the lack of dependency libraries, in this case, you can consider using aptitude install to install, it will automatically install the required dependencies in one step.

One of the special problems I encountered was that the aptitude in the system was missing, so I needed to use apt-get install to install the aptitude first, and the installation prompted that the dependency was missing libstdc++6, which looked like a dead loop. So use apt-get download and dpkg-I to manually download the libstdc++6 package for installation, and the installation process depends on a specific version of gcc-4.9-base, so use apt-get install to install it, then go back to install libstdc++6, and finally install aptitude, done!
