Clash Royale CLAN TAG #URR8PPP up vote 0 down vote favorite I'm trying to make changes to an OpenVPN connection via sudo nm-connection-editor . On the VPN tab, save is greyed out unless I put text in the username field. With this behavior I cannot save changes that have been made elsewhere. Most of the changes I want to try are on the Advanced tab. As a test I put a name in the username field and could save, but for that connection, username should be empty. Now I can't save again unless text is present. Empty quotes allow me to save but prevent the normal use dialog from appearing that would prompt me for phrase and one-time-password. I saw a solution that suggested checking the "All users may connect to this network" but that didn't help in my case. I saw another solution suggesting to edit NetworkManager.conf but the suggested parameters are not present in my file. I'm running $ gnome-shell --version GNOME Shell 3.22.3 $ cat /etc/redhat-release

What do mean by empty column lines? If you just want to print both columns then the man page for awk or google will help you. You're on the right track. – Na

Clash Royale CLAN TAG #URR8PPP up vote 1 down vote favorite If I am applying yum install -y --security and a package is updated; how is the package "marked" as a security update? For example, lets say I have a package blah that I maintain, its current version is 1.18.3 . If I build a new package as 1.18.4 is it automatically a "security" package? If not, how/where is the documentation to mark the package as "security" update? centos rhel security rpm packaging share | improve this question edited Apr 10 at 1:42 asked Apr 10 at 1:22 user1529891 1,847 5 20 42 If you're building your own packages, you could also put all the security updates in a dedicated repository. – Cristian Ciupitu Apr 10 at 3:20 add a comment  |  up vote 1 down vote favorite If I am applying yum install -y --security and a package is updated; how is the package "marked" as a secur
