yum update experience - the most reliable way

I realized that sometimes the yum tool does not offer all new package versions being available for upgrade when running

.

So I tried several methods to optimize the upgrade process and thought, it can be a good idea to share the one with the highest success rate.

It is recommended to perform every update and upgrade action from a virtual console by pressing Ctrl+Alt+F3 after booting on login screen.

It turned out that rebuilding the package cache from scratch by executing

and is an advantage.

Even though it is not necessary ... after successfully upgrading the packages I always reboot the system to restart all processes and services.

The benefit : a perfectly stable running operating system ! I am curious to know if there are alternative ways to achieve the same reliability ?
