> Since you have installed java manually, without the package manager, it has no way of knowing it shouldn't install java from the archive.
When Java is installed, the following returns a 0 value: java -version > /dev/null 2>&1 && echo $? >From a script, detecting Java is simple: -- #!/bin/bash echo -n "Java is "; java -version > /dev/null 2>&1 if [ "$?" != "0" ]; then echo -n "not "; fi echo "installed." -- The package manager technically *can* detect whether Java is installed (either as a package or manually), but it might not be worthwhile. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1450950 Title: Package dependency on Java To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-cuda-toolkit/+bug/1450950/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
