Re: problem installing some apps
 

If you want some help on this you are going to have to be a bit more specific. The problems you are encountering makes it sound as though you aren't using the standard repositories? If you are using testing or dev then you ught to be aware of the potential issues and how to put things back to standard if required.

If you can post the applications and repositories then someone might be able to help you out.

To be honest i came crashing into maemo/linux based OS when i got my 900 so i am probably doing all sorts of things i shouldnt be lol.That said do like to dip in on extras and devel, so how would i put it right if it all went belly up?:Thanx for the reply and the pointers.

Re: problem installing some apps
 

there's no standard way to "put it right" again, other than flashing the firmware and resetting the phone by that. that will definitely fix all problems caused by -testing or -devel packages (unless you reinstall everything after flashing of course).

other than that, you have to be more specific about your problem, as Fargus already told you. which packages have errors? which dependencies are missing?

Re: problem installing some apps
 

I think i am getting the idea (sort of lol ).The offending app was called stellarium and the conflict error reports soomething like this libqt4-maemo5-maemo5(4.6.0~git20100111-0maemo).Hope thats the right way to say it.

Re: problem installing some apps
 

this is an error due to the upcoming release of Qt 4.6
there have been a few mixups in the -devel repository because of this.

here's the package page for the latest version of stellarium.

it needs libqt4-maemo5-core (>= 4.6.2~git20100203), but you seem to have installed an earlier version of libqt4-maemo5-core (4.6.0~git20100111-0maemo), probably because of another software package that you installed.

this is something that can happen when you use the -devel repositories, and it's exactly the reason why it's not recommended for beginners to use it.

try to get rid of all the current libqt4-maemo5 packages with versions > 4.6.0, then stellarium should be able to install.

maybe
will remove all libqt4-maemo5 packages if the original application that needed them has been deinstalled.
if that doesn't work, you'll have to do it by hand:
the first command shows you every libqt4-maemo5 package, then you use each of those names as argument for "apt-get remove" so they get deinstalled.

thanks for the clean up tip.Helped me with the app problem and showed me how to clean up some stuff no longer needed at the same time.Cheers
Just to double check this command deletes packages that are no longer needed as the app they were used for has been uninstalled.right ?
