After image upgrade (18.06.2->18.06.4) LUCI login does not work

I upgraded my firmware image while keeping the configuration settings.
The router was fine, but two things I find odd:

  1. the software packages were gone and not re-installed automatically, I would have expected that somehow

  2. LUCI did not let me log in, but the root account login via SSH was working fine.

After reading in the forums I found a solution:
okpg install luci-ssl(-openssl)
append to /etc/config/uhhtpd:
config httpauth 'prefix_user'
option prefix '/'
option username 'root'
option password '$p$root'

I hope this helps some other souls who run into this problem.
