This past Halloween weekend I decided to upgrade my laptop from 10.04 to 10.10 (). Overall the process seemed fine, however I ran into a few issues so far :
1- Eclipse plug-ins (ie cdt, andriod) were caught in a limbo state. Eclipse showed that they were installed but the IDE wasn't using them correctly. For example, I could not directly edit a c file from a recent project - instead gedit was launched as the editor. Quick fix: renamed .eclipse folder home and reinstalled the plug-ins within the IDE. Also needed to remove $WORKSPACE/.metadata/.plugins/org.eclipse.cdt.make.core/$PROJECT.sc as it was linked to i486-linux-gnu which no longer exists (update created i686-linux-gnu) - was getting "invalid path" errors.
2- Firefox would crash when loading. Quick fix (after some Googling): removed the Open JAVA Icetea plug-in.
Permanent fix: install Sun JAVA plug-in for Firefox
- add "deb http://archive.canonical.com/ubuntu maverick partner" to /etc/apt/sources.list
- $ sudo apt-get update
- $ sudo apt-get install sun-java6-plugin
- $ sudo update-alternatives --install /usr/lib/mozilla/plugins/mozilla-javaplugin.so mozilla-javaplugin.so /usr/lib/jvm/java-6-sun/jre/lib/i386/libnpjp2.so 1
