pi4j not unpacking about pi4j-v1 HOT 3 CLOSED

Hi Martin,

I have not seen or heard of that particular issue before. While you do need 0.0.5-SNAPSHOT to support the Oracle JDK SE8 JDK, the installer package is the same. You can try using the newer one, but not sure if it will work for you.

https://oss.sonatype.org/content/groups/public/com/pi4j/pi4j-distribution/0.0.5-SNAPSHOT/

See this page for install / uninstall commands:
http://pi4j.com/install.html

Make sure to run the uninstall command first before trying to install again.

Hi Martin,

I encountered a similar issue today where I could not install a Pi4J .deb package on one of my older Pis.
The problem was that a previous version of Pi4J was not uninstalling cleanly due to a removal script failure.

I was able to use these commands to force the uninstall.

sudo rm /var/lib/dpkg/info/pi4j.prerm
sudo rm /var/lib/dpkg/info/pi4j.postrm
sudo dpkg --remove --force-remove-reinstreq pi4j
sudo rm -r /opt/pi4j

After this, I was able to install a new Pi4J .deb package using the instructions here:
http://pi4j.com/install.html

To really fix this issue, I should add additional logic to the install/uninstall scripts to handle additional edge cases such as the pi4j directory not existing on uninstall attempts.

Fixed in latest 0.0.5-SNAPSHOT
