For TW, Leap 15/15.1, I have a script that automates the download all the way to install with one command and your sudo password. But, it depends on easyoptions and alien. So, if you can get alien from TW:Utils (very easy), I can send you the script (or put it on github). As an example, to automate the whole thing, it would go something like this:
get-mc --build 44 -i
Some other options it allows:
Download the MC DEB and optionally convert to RPM
get-mc --build=NUM [option]
Options:
--version=NUM MC Version (25)
--major=NUM Major (0)
--build=NUM Build (Required)
--rpm=PATH Where to build the RPM ($HOME/rpms)
--deb=PATH Where to download the MC deb ($HOME/Downloads)
-d, --download Do not build the RPM, download only
-c, --check Checks the MC ca-certs setup
-i, --install Initiate install
Note the option to check the certs because on more than one occasion, I've had TW updates replace the certs stuff, which is to be expected, frankly.

MC link => /etc/ssl/certs/ca-certificates.crt
CA-CERTS => /var/lib/ca-certificates/ca-bundle.pem
