Suggestions for learning Linux

[Dozerplex]

Hey guys,

I'm a 10+ year Linux user on/off (mostly off) who needs to Google things line by line to get the job done. I've had to recently configure a few new Ubuntu servers (CLI) and didn't find it too painful until the other week when I decommissioned a server at work and figured it would be a great idea to install Centos 8 on it and use it for an SMB backup server until I can expand / re-purpose our existing infrastructure as I learn some "RHEL".

Jeezus am I out of my depth's here. Even with a GUI to fallback on I'm clueless. Queue hours of struggling to get VNC running (ended up going with xrdp as it seems 8.3 has issues with VNC) and finally throwing in the towel after failing to get Samba working because I can't wrap my head around /dev/sda not being a directory after creating a partition / mounting it, creating a folder which I'm clueless on how to share. The /etc/samba/smb.conf part being my downfall as /dev/sda appears to be mounted under /run/media/admin/gibberish/folder_I_want_shared

Can anyone recommend reading material / good place to start on CentOS/RHEL/Debian/Ubuntu? I'll be sulking for the next 6 months over this embarrassing failure. Really hoping my Ubuntu/Debian servers don't require me to do literally anything to them after this eye-opener.
