[Bug 392922] Re: Update manager starts when the apt download lock isn't yet released

[Shannon]

The update manager should not start in this case. It should wait until
all patches are downloaded, then pops up.  Restart the update manager
does NOT solve my problem, as described Dario.... It simply needs to
wait until lock is released!

I am surprised to see this 2-year old bug is still alive. Hope it is
fixed precisely for Precise release!

Title:
  Update manager starts when the apt download lock isn't yet released

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

Bug description:
  Binary package hint: update-manager

  steps to reproduce:

  -have selected "Download the updates but don't install them automatically" (i've also checked to check for updates every day)
  -wait for updates to happen
  -wait for updates to be downloaded in background
  -when update-manager is launched, click on "install updates" (and eventually insert the password)
  -a popup shows up, reading(in italian):

  "E: Impossibile ottenere il lock /var/cache/apt/archives/lock - open (11 Risorsa temporaneamente non disponibile)
  E: Impossibile bloccare la directory di scaricamento"

  workaround: close update-manager, reopen it, click on "install
  updates"... it'll work fine

  this is the error that happens when apt-get or synaptic, or
  "add/remove software" is running... but this isn't the case since by
  closing and reopening update-manager, which is the only one running,
  the problem goes away...

  i guess that it's due to the fact that it's launched after downloads
  have been completed, but before the process that has done the
  downloads has released the apt lock...

  due to the length of the second step to reproduce, i'm not 100%
  certain that this bug shows up with all updates, but i've definitely
  seen this bug more than 2 times...
