[Bug 876519] Re: Not able to upgrade friom 11.04 to 10.10

[Gabriel]

I tried doing it on command line :

$ sudo do-release-upgrade -p

Although I get this:

WARNING: Failed to read mirror file

it is able to get the package data :

Get:13 http://mirror.switch.ch oneiric Release [40.8 kB]

but then something happens:

Fetched 15.8 MB in 6s (663 kB/s)

Do you want to start the upgrade?


52 installed packages are no longer supported by Canonical. You can 
still get support from the community. 

26 packages are going to be removed. 420 new packages are going to be 
installed. 1289 packages are going to be upgraded. 

You have to download a total of 127 M. This download will take about 
2 minutes with your connection. 

Fetching and installing the upgrade can take several hours. Once the 
download has finished, the process cannot be cancelled.

I tried other mirrors same thing. The thing is that it worked before I canceled, and I can connect to the server using the browser, and the update manager proposes updates when there are some available and I'm able to upgrade (had 2 this morning, went ahead and tried, they succeeded). I'm a bit lost here...

Title:
  Not able to upgrade friom 11.04 to 10.10

Status in “update-manager” package in Ubuntu:
  New

Bug description:
  I started the upgrade manager (11.04 to 11.10) and had to stop during
  the "Getting new packages" part. I then later on re-started the
  process and libimobiledevice2 was upgradable, so I decided to upgrade
  it before finishing the system upgrade. Bad choice as now the system
  upgrade process stops doing anything at "Getting new packages"... I
  then tried downgrading libimobiledevice2 from 1.1.0-3ubuntu1 to
  1.1.0-3, but that doesn't help...

  While I agree that wasn't the best thing to do, I think in a system
  upgrade is stopped you should have a way of restarting it from scratch
  or continuing where it left off; currently it continues from what the
  UI says. I think it build an original list of packages to be upgraded
  and now it's stuck because of a mismatch.

  BTW, running "ubuntu-bug update-manager" stays stuck in the
  "Collecting problem information" step, and "ubuntu-bug" then choosing
  "other" closes with an error that a PID has to be given, even though
  there is no visible way of providing that.
