OK, I got my N900 for 3 days now and I am totally a newbie for LINUX. I tried to install aMSN and FM-boost yesterday, for some reason they both failed during installation. I cannot reinstall or remove them. Then I tried to reinstall aMSN in console and put command in XTerm:'apt-get install amsn', seen from this thread: http://talk.maemo.org/showthread.php?t=36659.
Then it starts to download and install aMSN untill it says

'Reading database....22851 files and directories currently installed.)
Removing fm-boost ...
gtk-update-icon-cache: Failed to open file /usr/share/icons/hicolor/.icon-theme.cache:file exists
dpkg:error processing fm-boost (--remove):
subprocess post - removal script returned error exit status 1
Errors were encoutered while processing:
fm-boost
E: Sub-process /usr/bin/dpkg returned an error code (1)

It seems problems are caused by fm-boost now, I tried everything I know to remove or reinstall fm-boost but failed


Also my N900 keeps disconnecting from my home router after no operating for a while. I read from a thread that it's something to do with powersave mode. I change that to intermediate and even to off, it stays a bit longer but still disconnects, any idea?

I am so newbie, Please help!! Thanks.
