Hy, my problem in general is about network almost working.
I'm using 12.10 ubuntu (installed on a new HDD after using 12.04 wich didn't work too well) on Dell Latitude D620.
All problems start with Software Updater wich shows me 40 new updates waiting to be installed. After pressing install now I get a error "system error". Pressing report error it gives me another one something like "ubuntu experienced a software error", after pressing report error it gives me yet another one telling that program crashed unexpectedly. After clicking leave closed it askes me about a minute later my password to report a problem. In this time software updater just hangs there - not responding, not crashing - just chillin'.
Also software center doesn't allow me to install anything - clicking install it just doesn't do anything whatsoever.
Only thing that let's me do anything in matter of sofware is synaptic package manager.
Also my transmission (BitTorrent client) downloads everything for about a minute or so and then gradually closes all connections (wihtout any warning or anything). Both for uploading and dowloading. New connection is possible but those as well get disconnected in about a minute or so. Restarting transmission gives me another minute of up/downloading.
Problem keep coming - sometimes my wireless connection decides to just go away - it does not disconnect connection, it just goes away. The icon shows no connection but clicking on the icon tell me i'm connected. After closing connection thru pressing a button on my laptop and then switching it on again the wireless network comes back.
Thing that is problably not the problem with network but someone might find it useful for me to mention is that I can't backup my system - namely because backup keeps asking me the encryption password (not saying it's wrong but asks me for the password - starts the process of prepearing for backup - asks me for the password again and starts the process again and so on and so on). Password is correct - I know that much.
Overall I have to do a restart on my computer at least once a day to use Wifi in general (sometimes the switch on the laptop doesn't do anything at all).
On Windows XP (sorry for mentioning it on ubuntu forums) all worked well.
Really don't like to go back on windows a Linux is a great platform to learn Computer Science on and has a lot of extremely useful tools and apps for free. That being said - I really can't use my computer like this also.
Thanks for any help you could give me!
PS! Updateing and upgrading doesn't work thru terminal either.
PPS! Problems I had with 12.04 still remain with 12.10 in network-wise. My unsolved post about 12.04 IM connection problems (still have the same problem in 12.10 http://ubuntuforums.org/showthread.php?t=2098635 )
