Verifying/fixing a failed (?) upgrade to 13.04

+1 vote
639 views

Yesterday I upgraded a machine from 12.10 to 13.04 using the GUI from
the update-manager. Something mysteriously died towards the end (I
got some /var/crash/_whatever) & I can't figure out how to tell if the
upgrade worked or not. When I log into the machine it shows this:

Welcome to Ubuntu 13.04 (GNU/Linux 3.8.0-19-generic i686)
...
Graph this data and manage this system at https://landscape.canonical.com/

New release '13.04' available.
Run 'do-release-upgrade' to upgrade to it.

But do-release upgrade does nothing:

/home/xxxxx $ sudo do-release-upgrade
[sudo] password for xxxxx:
Checking for a new Ubuntu release
No new release found

and aptitude update && aptitude safe-upgrade do nothing either. I've checked that all the entries in /etc/apt/sources.list and sources.d/*.list have "raring".

How do I verify that my system is upgraded? If it is, how do I fix the "New release" message?

Does
sudo apt-get update && sudo apt-get dist-upgrade
achieve anything or produce any errors?

I always forget about apt-get these days, but it does nothing:

/home/xxxxx $ sudo apt-get update
....

/home/xxxxx $ sudo apt-get dist-upgrade

Remove the file
/var/lib/ubuntu-release-upgrader/release-upgrade-available

OK, but how can I tell what else got missed in the mostly-done upgrade? What part of the release upgrade is supposed to remove that file?

The aptitude equivalent would be "aptitude update && aptitude
safe-upgrade && aptitude full-upgrade".

Virutalbox for ubuntu 13.04

I installed virtualbox from the synaptic package manager and then loaded windows 7 and also installed the extensions pack. For some reason when I plug in usb devices they can't be accessed by the virtual windows 7. Every time it says failed to install drivers for the usb device when I plug in a usb memory stick, or iphone or etc. What can I do to get usb support to work, the usb devices are shown in the lower portion of the virtualbox window but won't work in windows 7.

kate crashes when konsole is installed (Ubuntu 13.04)

I am using kate in a gonme/unity environment.

Now on two different computers (not on an some others) I have the problem, that kate crashes as soon as I open a file. This only happens when:
- the "Terminal tool view" is activated
- a terminal view is open
- konsole is installed in the system using apt-get

as soon as konsole is uninstalled from the system, kate works fine, but the (very handy) terminal tool becomes useless.

can anybody point me to a solution?
