Yesterday I build the latest git, version 18.104.22.168. for Ubuntu Intrepid on my PPA. This morning when I wanted to upgrade my own machine, I ran into a small problem. It turns out Launchpad has signed my repository and in order to upgrade you’ll need to add the key to the trusted apt key list.
These are the steps to add the key:
gpg --keyserver subkeys.pgp.net --recv-key 551CE2FB4CBEDD5A gpg --armor --export 551CE2FB4CBEDD5A | sudo apt-key add -
The output you’ll see:
gpg: requesting key 4CBEDD5A from hkp server subkeys.pgp.net gpg: key 4CBEDD5A: public key "Launchpad PPA for Peter van der Does" imported gpg: Total number processed: 1 gpg: imported: 1 (RSA: 1) OK
You are all set now.
