Question

I've tried installing Sun JDK from sudo add-apt-repository ppa:eugenesan/java, it failed with the following:

Oracle JDK 7 is NOT installed.
dpkg: error while cleaning up:
 subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
 oracle-java7-installer

So apparently it's trying to fetch a bad URL. I've installed Java manually, but now the package is stuck as a half-installed and every time I apt-get install anything, the error appears again.

apt-get install -f shows "1 not fully installed or removed." package and fails with the same error. I've tried dpkg -P oracle-java7-installer, but it fails as well.

How to remove this half-installed package?

Solution 1

Awww yeahh.. I've been able to finally remove after finding this post the following way: sudo find /var/lib/dpkg -exec grep -l "oracle-java7-installer" {} \; showed a bunch of files, I've added exit 0 to first line by typing sudo gedit /var/lib/dpkg/info/oracle-java7-installer.prerm, saved file and closed gedit. Finally, after I was back on command line, typed sudo dpkg -P oracle-java7-installer and it worked.

Solution 2

sudo rm /var/lib/dpkg/info/oracle-java7-installer*

sudo apt-get purge oracle-java7-installer*

sudo rm /etc/apt/sources.list.d/java

sudo apt-get update

sudo add-apt-repository ppa:webupd8team/java

sudo apt-get update

sudo apt-get install oracle-java7-installer

• Are PPA's safe to add to my system and what are some "red flags" to watch out for?

Does not work. Marked the package for removal, clicked "apply" - the package is still there. I'm guessing it gets the same error

By the way, if you want to fix the half-installed package rather than manually installing Java, the answer here should facilitate that.

Worked fine! In my case I had to edit /var/lib/dpkg/info/oracle-java8-installer.postinst and add an exit 0 there.

I would love to work out how I get to know to look for that first line. It's bugged me for weeks
