I'm on Xubuntu/ Ubuntu 16.04 and I am trying to install libssl0.9.8:
sudo apt-get install libssl0.9.8
Error:
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package libssl0.9.8 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'libssl0.9.8' has no installation candidate
There has been a version bump for Xenial Xerus:
sudo apt-get install libssl1.0.0
is what you need...
References:
That error occurs when a package is not available from the repositories. In other words, that package does not exist for Ubuntu 16.04 (Xenial). See it here. It stops at Trusty (14.04)
If you really need to install it, download the package manually and install. This is how:
Download the package for your particular architecture (32/64bits) from here.
Extract the file(s).
Open a terminal, go to the extracted folder and run:
sudo dpkg -i file.deb
sudo apt-get install -f
(The latter command will install any dependency libraries needed, as listed here)
NOTE: Installing old packages and their dependencies can be risky, as it can conflict with current libraries. There might be a reason why the package is not available for your Ubuntu release.
Download and install the trusty package manually:
i386: http://packages.ubuntu.com/trusty/i386/libssl0.9.8/download
amd64: http://packages.ubuntu.com/trusty/amd64/libssl0.9.8/download
