Comment 4 for bug 926548

I've submit https://bugs.launchpad.net/ubuntu/+source/software-properties/+bug/930478 and was referred here as a duplicated bug.

Issue arise on my Precise Pangolin 64bit. Just want to add although I wasn't able to add-apt-repository in the terminal, I was able to ass ppas in Software Centre. It just if you run updates in the terminal, it would post error that it unable to verify the signature/sign of the ppa (...if you accept to continue, it would run nonetheless).
