i am new to linux and have little to some of information on commands at this point. I have managed to install ubuntu 10.10 about a 4 days ago and have successfully installed all the updates that same day- via the terminal. Now today i got 5 updates and wil not let me install them by any commands i give it. upadate manager say requires installation of untrusted packages. the terminal say:
sudo apt-key adv --recv-key --keyserver keyserver.ubuntu.com 40976EAF437D05B5 Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --secret-keyring /tmp/tmp.UWSzw2Lg76 --trustdb-name /etc/apt/trustdb.gpg --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --recv-key --keyserver keyserver.ubuntu.com 40976EAF437D05B5 gpg: requesting key 437D05B5 from hkp server keyserver.ubuntu.com ?: keyserver.ubuntu.com: Connection refused gpgkeys: HTTP fetch error 7: couldn't connect: Connection refused gpg: no valid OpenPGP data found. gpg: Total number processed: 0
can someone help me fix this.
