Hi all. I erased my MacBook Pro circa 2011 today so I can donate it. I tried reinstalling High Sierra twice and got the following screen:

After restarting in internet recovery mode I ran First Aid from this screen:

The internal OS X Base System is not mounted. I‘m not sure what to try next. Anybody have any ideas?

It's been so long since I installed High Sierra. I forget what the APFS rules were. Is it something like:
1) new install = APFS
2) existing install = HFS+ or APFS
?

Mine is HFS+, it could have been a Sierra install updated to High Sierra.
I have Mojave on HFS+ up to 10.14.3. Then APFS for 10.14.4, 5, and 6.
