flashplugin-installer fails to download adobe-flashplugin

[Nitesh Mistry]

Since last 3-4 updates of flashplugin-installer on both my installs of Ubuntu 12.04 and Kubuntu 12.10, I am facing the following problem:
1. 'sudo apt-get upgrade' shows that a new version of flashplugin-installer is available (along with update to other packages)
2. When I go ahead with the update, it downloads the flashplugin-installer from 'http://us.archive.ubuntu.com/ubuntu/ quantal-updates/multiverse'
3. Further it shows 'Preparing to replace flashplugin-installer ... (using ...)'
4. Then 'Unpacking replacement flashplugin-installer ...'
5. The next line is 'flashplugin-installer: downloading http://archive.canonical.com/pool/partner/a/adobe-flashplugin/adobe-flashplugin_11.2.202.280.orig.tar.gz' - Here it remains stuck for sometime. I remember earlier it used to show the process of downloading the adobe-flashplugin at this stage, but not since this problem is occuring.
6. After remaining stuck at the above message for some time, it shows 'Installing from local file /tmp/tmpzjbHF5.gz' and proceeds with installation of other packages and exits.

I don't know if the new version of the plugin is installed or does it revert back to the last installed version of the plugin. I guess the link in the installer package is correct because it shows up the new package when I open the link in the browser.

Also, I have no problem playing flash files in the browser like viewing videos on youtube.

'apt-cache policy flashplugin-installer' gives the following output:
