On installing juniper version with devstacks it constantly giving this error I have tried of updating the public key which expired but it does not update the expired key.
I have tried →
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 69464050
but it always gives this output–>
gpg: key B41E5E3969464050: “edX Inc. (edX PPA) email@example.com” not changed
gpg: Total number processed: 1
gpg: unchanged: 1
this error never came before on setting juniper I have installed juniper many times before but this is the first time for this error came.
