[Bug 224539] Re: Failed to lock /var/cache/apt/archives/lock

[oriman]

It effects me as well with Ubuntu 9.04.
The Update Manager offers me [Partial Upgrade]. I click it, wait for the downloading to finish, and get a screen that offers me to [Start Upgrade]. I click it and immediately receive this error message.

I tried to run the Update-Manager as root but got the same error.

A [Retry] button would be good, allowing me to try and remove this lock
before the Update Manager starts to undo all changes.

Is there a work-around?

  Hello,

  I started kubuntu upgrade from 7.10 to 8.04. Upgrade was downloading
  slow and I had to switch off my PC. I closed upgrade manager in the
  middle of package download. After I started again I got this error
