There are two solutions to installation failures caused by dependency library version issues:

1. The source needs to be updated, as follows:

libssl-dev: Dependency: libssl0.9.8 (= 0.9.8o-1ubuntu4) But 0.9.8o-1ubuntu4.4 is about to be installed

Solution:

Enter "System->System Management->Update Manager->Settings", select the "Update" tab in the pop-up "Software Source" dialog box, select the four check boxes under "Ubuntu Update", and close Then execute the following command in the terminal:

sudo apt-get update

2. Use aptitude package manager to solve this dependency problem. With aptitude, you can choose the appropriate version and matching software to install

libssl-dev version problem cannot be installed: Depends: libssl1.0.0 (= 1.0.1t-1 deb7u2) but 1.0.1t-1 deb8u6 is to be installed
