New to Manjaro and - even after 15 years - new to Linux. Tried installing 18.0.4 on my (old) MSI 970A-G43 mobo. (Latest BIOS.) I got the hang at 93% which others have reported in the past.
As others have noted, it appears to be a NIC problem, since the NIC goes off line just as the Installer starts the pacman-mirrors -Syyuu stuff. (Per the log file, below.)
I didn't see a way to disable a possible offending RealTek driver from within Manajaro live. (Booted from USB.) For example, someone said to go to Hardware to remove it. But I don't see any category for the NIC in Hardware. (And, too, mine is not a WiFi NIC.)
Per a suggestion in this forum, I ran sudo -E calamares -d to capture a log file.
I don't see a way to attach a file here. So here's the link to it:
I'm not looking to become a Linux geek. I would just like to get Manjaro installed so that I can run Resolve. So if you have a suggestion for me, please explain step by step what I need to try.
