After linux is installed, many new users are eager to find the source of the upgrade and related configuration problems, and then upgrade it. I have seen black screen or boot failure examples after the upgrade, which is enough to quit. In fact, we use linux for learning. As a veteran of the little white, there is no need to upgrade your system. Learning linux won't cause any problems because the version number of a software is small.
We can often see some people see a crazy change from fedora8, and then wait for the appearance of 9, and then change it to 9 immediately. Unfortunately, the machine is really disappointing, and the installation process is almost the same, the error message returned when the error message returned. We do not use linux for fun. Learning linux is not just a small update. (Except for serious bugs, of course). For example, if a newbie learns shell, all you need is a complete bash and a kernel. The installation of many things takes a lot of time to upgrade, which is always a thankless action. (If you want to show off your linux, you can do it. But if you use linux to show off, you can still use windows)
A officially released version of linux is a complete image that is well assembled with what the system needs. For a Tom, you won't even use a lot of things in a few years. What is the significance of crazy upgrades? When writing the kernel, Mr. linus also said that a Linux kernel should not be busy upgrading the version number. It is important that it can be used stably.
