Hi,
I tried to install IDE 4.7 / SDP 6.5.0 on Ubuntu 9.04 LTS, 9.10 and 10.04LTS. No success.

I started with 9.04LTS and the installation stopped at 15% and stays forever, I had to break it.
After a new attempt, the installer tells me: product already installed.
I then removed the envars QNX_JAVAHOME, QNX_HOST, QNX_TARGET and QNX_CONFIGURATION from the shell.
I removed all the envars setting from /etc/profile (including the one from 6.4.1 installation)
I deleted the ~/.momentics directory from a 6.4.1 installation.
I deleted the /opt/650 directory.
I checked all files in /etc/qnx regarding artefacts from 6.5.0 -> nothing.
I then logged out and in again.

Same problem.
I tried that with all Ubuntu versions listed above.
Uninstalling Momentics is realy a pain since years!

cheers,
Peter
