install fails randomly

[didi156]

We use the latest symfony 2 (master branch) with composer for 2 projects and regularly have troubles when deploying on our servers.
The issue seems to be the same as discussed in https://github.com/symfony/symfony-standard/issues/278
It's marked as solved there, but I can't confirm that.

Some version info:

lsb_release -a

The output of a typical failed install (here starting with empty vendors dir):

As you can see, the 1st time it fails for bundle "assetic", on 2nd try that one succeeds, but another one fails. If I go on and retry again and again, I sometimes manage to get through. Sometimes I also get stuck at a bundle for 10+ times.

As you may see, the installed php package is not the one from default Ubuntu 10.04 repository bcs 5.3.2 isn't supported anymore by Symfony2 (?)
I tried on another server with Ubuntu 12.04 and default PHP package installed, didn't have this issue there. However on the vServer used for deployment, I can't switch operating system for some time to come.

Any clue what's going on here?

Could you try to update composer see if it helps? It now includes symfony/symfony#4970 which supposedly fixes that problem.

@Seldaek
