Since I upgrade to the latest version of Ubuntu, cannot install Java OpenJDK needed to compile android custom roms, when I run sudo apt-get install openjdk-7-jdk appear the following error:
Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: openjdk-7-jdk : Depends: openjdk-7-jre (= 7u51-2.4.6-1ubuntu4) E: Unable to correct problems, you have held broken packages.
It should be noted that Ubuntu 16.04 no longer supports versions openjdk-7of
The one I did on 16.04 was:
For OpenJDK 8.X
sudo apt install openjdk-8-jre
For OpenJDK 9.X
sudo apt install openjdk-9-jre
Note: There was no openjdk-6-jre nor openjdk-7-jre for me on Ubuntu 16.04. Also there is NO need to install Oracle JDK (Actually OpenJDK is much better than Oracle one for me).
