I have recently asked about how to upgrade
ghostscript to a version that is available on 15.04 but not on 14.04LTS (which I have). On this site there are numerous almost identical question regarding different packages, a few examples include:
- How to upgrade to a newer version of a package than is available in the repository?
- How to upgrade a single package using apt-get?
- How to upgrade to a later version of Remmina than is in Repository
- Upgrade tmux from 1.8 to 1.9 on Ubuntu 14.04 (on Stack Overflow)
So I thought it would be very useful in general to know: is there a general, automated way to upgrade a package, including all its dependencies, to a version that is newer than Ubuntu's repos? Is this more easily done if the newer version exists in more recent Ubuntu releases?
