I install MCUXpresso inside an Ubuntu 16.04 64-bit VM with minimum dependencies and noticed the following error in the console when trying to launch dialog boxes (which still appeared to work however).
(MCUXpresso IDE:17774): dconf-WARNING **: failed to commit changes to dconf: Failed to execute child process "dbus-launch" (No such file or directory)
This is caused by the missing dependency on dbus-x11, which I fix with the following.
apt-get install -y dbus-x11
Thank you for your feedback. It sounds like you have installed a more minimal install of Ubuntu than we have done during our testing. We'll log this dependency issue for fixing in a future IDE release.
