Error gpg key not found or not match?
When you run the update managers like yum or apt-get they get the gpgkeys for repositories, when they don’t, the update manager will show this error, to solve the problem manually download and install the gpg key for that repo with: dpkg -ivh your_gpg_key.deb rpm -ivh your_gpg_key.rpm Or disable the gpgchek in the update manager with making 0 or adding a hush.
