I have problem executing apt-get

If all other options fail, do what i did. other info, i got myself here by trying to install the rpm jdk8 pachage on linux mint 17(ubuntu)

sudo rm -ri /usr/java/

it will ask for password then ask to make sure you want to delete that directory. press "y" and enter/return

then open /var/lib/dpkg/info/ as root and delete any files with "jdk1.8.0-xx.xxxx" once done deleting run

sudo dpkg -r --force-all jdk1.8.0-45

if you are trying to install jdk 8. this page will be of help because it worked for me.(linux mint 17 cinnamon 64bit) http://tecadmin.net/install-oracle-java-8-jdk-8-ubuntu-via-ppa/

Try creating the missing file as suggested here. Follow:

sudo mkdir -p /usr/java
sudo touch /usr/java/aa
sudo touch /usr/sbin/alternatives
sudo apt-get remove jdk1.8.0-40
echo "" | sudo tee /var/lib/dpkg/info/jdk1.8.0-40.postrm

Then un-intall java by:

sudo dpkg --purge --force-all jdk1.8.0-45
