that's a plugin, so might have left it out during packaging...adding to 2do

keep the reports coming, that's the only way we can get a good, healthy version to extras !

We filed one and it has already been set to critical: http://bugreports.qt.nokia.com/browse/QTMOBILITY-1664

Upped a new version, should have the missing organizer plugin and the prf file fixed, feedback welcome.

it said some plugin will keep back
some can upgrade some cant

Can you be more specific ? E.g. copypaste the error or post a screenshot ?

The following packages have been kept back:
libqtm-12 libqtm-12-contacts libqtm-12-declarative
libqtm-12-location libqtm-12-messaging
libqtm-12-multimedia libqtm-12-publishsubscribe
libqtm-12-serviceframework libqtm-12-systeminfo
libqtm-12-versit libsdl-mixer1.2 wifi-switcher

That's not a problem per se, that's just the consequence of the applications you already have installed. If you do an apt-get install libqtm-12 manually, it should upgrade (barring any applications with wrong dependencies)

thanks
solved

how to upgrade without having to autoremove my other apps???

qmltube has a fixed version dependency (= 1.2.0-0fn~fremantle0) so no upgrades possible. I suggest you contact the qmltube author/maintainer and ask whether he really needs that EXACT package version.
