I wanted to install OpenJDK-8 on Ubuntu 14.04. So as described here I tried to find the correct name of package (which is openjdk-8-jdk) and run these commands:
sudo apt-get update
sudo apt-get install openjdk-8-jdk
But I got:
E: Unable to locate package openjdk-8-jdk
So I went to Ubuntu Packages Search and Ubuntu Updates and searched for package. But I could not find any thing about trusty (14.04LTS) or trusty-updates. So I was sure there is no install able package to be installed on Ubuntu 14.04.
Of course after sometimes I suddenly found that package belongs to openjdk-r/ppa repository and added that:
sudo add-apt-repository ppa:openjdk-r/ppa
But I want to know how I can find appropriate repository (in above example the openjdk-r/ppa) before consuming times and waiting for chance?
Usually, I do as Jacob Vlijm said through a search engine DuckDuckGo/Google. Most of the time, they bring well results with users feedback from the web.
But not everything, in some cases I back to launchpad site itself which shows me always the final results:
Search with more keywords to minimize noise (other releases, arch's, ..)
Example: ppa openjdk-8-jdk amd64 trusty
Skip the top part (projects). The first one looks like what I want
amd64 build of openjdk-8 8u91-b14-0ubuntu4~14.04 : OpenJDK ...
Apr 22, 2016 ... “PPA for OpenJDK uploads (restricted)” team ... OpenJDK builds (all archs);
amd64 build of openjdk-8 8u91-b14-0ub... created ... Series: Trusty.
However, the link took me to a buildlog, on top-right area you can see Build details → → Archive → OpenJDK builds (all archs) which is the PPA link.
Check if the PPA still has that build for trusty, by setting the filter:
Overview of published packages → Published in: trusty then press Filter
