[Bug 830492] Re: Downloads should not lock apt

[Michael Vogt]

I close this as won't fix for apt and synaptic for now. I personally
think that its a good idea, but its at the wrong layer. I.e. there
should be something like aptdaemon or packagekit that you can tell do
queue another download and it should just do that. This may requires
some targeted changes in libapt as well, so I'm inclined for a
"whishlist" tag actually.

  Downloads should not lock apt

Bug description:
  It should be possible to download while installing, or download 2
  things at once.

  Currently an apt-get command with '--download-only' will lock apt
  (/var/lib/dpkg/lock). Synaptic even locks apt just by being open!

  Examples:
  * I might be updating my system. The update is still in the download stage, and I want to download and install a small package for something. Currently I would have to stop the download, install the package, and resume the download.
  * I'm installing lots of application from the Software Centre. While 1 app is installing the next should be downloading.
  * Run apt-get from command line while browsing software in Synaptic.

  To avoid multiple instances of apt downloading the same file, each
  partial file should have it's own lock (For example,
  /var/cache/apt/archives/partial/inkscape_0.48.1-2ubuntu2_i386.deb
  would have inkscape_0.48.1-2ubuntu2_i386.lock). It may also be
  necessary to prevent updating package lists (sudo apt-get update) when
  any download lock exists as well as apt's main lock.
