Hello
I successfully run: (as indicated in the web site)
sudo apt-key adv --keyserver keyserver.quickbuild.pearsoncomputing.net --recv-keys F5CFC95C
And installed trinity, but after a while when running
sudo apt-get update
Again I obtain:
Reading package lists... Done W: GPG error: http://ppa.launchpad.net lucid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 4DF9B28CA252A784
Did the key change?
regards
Uwe Brauer
