Thank you for your report. I was able to execute the command you supplied successfully. I'll attach my terminal log.
So since this looks like a local configuration problem, rather than a bug in Ubuntu, so I'm marking this bug as Invalid. You can find pointers to get help for this sort of problem here: http://www.ubuntu.com/support/community If you believe that this is really a bug, then you may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem, and then change the bug status back to New. ** Changed in: php5 (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to php5 in Ubuntu. https://bugs.launchpad.net/bugs/1083513 Title: installation IDN on PECL at PHP > 5.3 fails To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/php5/+bug/1083513/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
