I am using the 21.04 in my daily work with no issues as we speak.
I bought an new computer recently dedicated for my work and as a Plex server after work.
Since installation of the 20.10 version did not get the Realtek network Ethernet to work, I got the idea from internet that the newer kernel supported it.
I got the same trouble with 21.04, but managed to install a r8125 driver with help from a slow USB network dongle.
So now I am up and running and really like to work on a Linux computer vs my old MS10. Last time I played with Linux was in 1997. Then as now, the network card was my challenge.
My Plex server is gone down for the moment for some reason, but think I will let it be for a later reinstall when the system is more stable.
I do wonder if it is wise to do update every day as long as the system works with no issues.
My fear is that a update corrupts something vital, and that I can not start up the system again.
Any advice here would be great.
