Question No telnet no yum

[Jacek]

Hi, I need to telnet yahoo server to troubleshoot why my mails are rejected by them. But I can't either telnet on root, or user or install telnet by yum. On both I have "command not recognized"

Well, depending on your Linux distribution you'll have to use either one of those to install telnet:

apt install telnet

or

dnf install telnet

or

yum install telnet

You'll have to figure out which Linux distribution you have so that you'll know in the future whether to use apt or yum or dnf....

@leopixelstudios , that looks like a connectivity issue with the MariaDB repository mirrors. What you can try is to temporarily disable the repository:

dnf install telnet --disablerepo=mariadb

or you can update the repository source in /etc/yum.repos.d/MariaDB.repo.
