I tried installing Firefox, Java, and the icedtea plugin for i386 to use a web based VPN client (Junos Pulse for web), and it turned into a disaster.
Then trying to run upgrade failed… Sad day for my XPS.
Here’s how it got fixed:
E: Sub-process /usr/bin/dpkg returned an error code (1)
sudo -i dpkg -i --force-overwrite /var/cache/apt/archives/icedtea-netx_1.5-1ubuntu1_i386.debapt-get autoremove
apt-get update apt-get upgrade I've always been a RedHat/Centos/Fedora fan, but Ubuntu/Debian has grown on me, I blame Will B. and the Raspberry Pi project. My Desktop, laptop, control center, and IoT devices all run a form of Debian. 3 years of running Ubuntu/Debian and this is the first time things broke, whereas RedHat package issues have consumed many hours of hair pulling and cursing at the screen. This was a 5 minute fix because of a great community.
