[Maverick Alpha 1] An unhandlable error occured in aptdaemon

[Sergio Santoro]

I tried to install further languages in Maverick Alpha 1 but in package "aptdaemon" occured an error:

Traceback (most recent call last):

It seems that you have missed to copy the last and most interesting lines of the error message.

Please do so, if the error appears again

I have edited the bug description to include the last few erroneous lines.

I received this message with this morning's updates.

An unhandlable error occured

There seems to be a programming error in aptdaemon, the software that allows you to install/remove software and to perform other package management related tasks. Please report this error at http://launchpad.net/aptdaemon/+filebug and retry.

Same problem here, testing on Virtualbox with Maverick Daily:

Rebooted, had some problems with mounting /tmp said plymouth and ran checks and rebooted again. (Not sure if this is related). Booted to recovery mode, ran latest updates. Update manager works fine here.

hi! Sorry for my bad english... I developp application pytomtom and provided pytomtom.deb for lucid. unfortunately this package failed to be installed on maverick with ubuntu software center.

- first, i installed gdebi and it works fine !!!

- after this , i try to install it with ubuntu software center. It's seems to be the same bug...

Traceback (most recent call last):
  File "/usr/lib/python2.6/dist-packages/aptdaemon/worker.py", line 768, in simulate
    return self._simulate_helper(trans, status_path)
  File "/usr/lib/python2.6/dist-packages/aptdaemon/worker.py", line 851, in _simulate_helper
    size = int(deb["Installed-Size"]) * 1024
ValueError: invalid literal for int() with base 10: '243.1'

When i build this deb, in my "control-install" was notified: "Installed-Size: 243.1"
I deleted this ligne and it's works fine ! I could have installed my application on maverick with ubuntu software center. But bug has no desappear... i just have deleted information about size.

Hope this will help someone...

This is what i get ....

Media change: please insert the disc labeled
 'Ubuntu-Studio 10.10 _Maverick Meerkat_ - Release i386 (20101008)'
in the drive '/cdrom/' and press enter

But CDRom is not recognized.
Now I'm really screwed.
