software centre installation freezes while trying to install ubuntu restricted extras

[Joneil]

Installation in software center freezes at about 70% or so it seems when tryin to download and install the restricted extras in ubuntu 12.04 lts. There seems to be no way of undoing the installation or ending it, hence i cannot use terminal.

also affected, identical symptom.
hangs at about 70%, during "applying changes"

This hang in installation might have to do with the flash component, which also hung when i tried to install it from ubuntu software center alone (i.e. w/o the whole restricted extras package). I was trying the restricted extras package because i thought that might be a 'safer' way to get the flash component.

Status changed to 'Confirmed' because the bug affects multiple users.

i was able to install ubuntu restricted extras successfully from synaptic package manager

just for the cleanup of this bug, that shows up in 12.10, too:
close firefox when the installation freezes/hangs, it will continue and finish then.

the installation of the flash plugin needs firefox to be closed, but no message appears (we know this message from other operating systems, dont we? ^^)

I was having exactly the same problem:

Installing Restricted Extras, Ubuntu 12.04, HP Pavillion 6000, 64-bit.

The Ubuntu Software Center froze at about 70% of Restricted Extras.

I was researching workarounds, found this page, had decided to go back and use synaptic, and before I could kill the in-progress install....it kicked in suddenly and finished. I did not time it but I'm pretty sure it was well over 10 minutes; and I just clocked my internet down-link speed at 5.9 Mbps. I am wondering if perhaps there is some hangup at the server dishing up the Restricted Extras to Ubuntu Software Center?! I have no way of knowing if the source had been completely downloaded or my machine was waiting on more data. If Synapse is grabbing Restricted Extras from a different server that might be an explanation for why it works better.

At any rate, I did experience this stick, but then it finished installing; and the Ubuntu 12.04 was a totally fresh install on a newly formatted partition this afternoon (Restricted Extras was the second new thing I installed after Chrome)

Having this exact problem downloading Restricted Extras today and recent days and Firefox wasn't open. DVD discs not being read - it accepts the files with .VOB extension but not the others.
