For password, I used the same pw generated in my pw manager that worked before.
I found a post at Illegal instruction pour le script de postinstall sur raspberry pi 2
Command:
sed -i ‘s/import miniupnpc/#import miniupnpc/g’ /usr/lib/moulinette/yunohost/firewall.py
After running that command, post install was able to move forward and needed to select a new domain.
I think my next issue is the update process stalling out during the update of php7.3.
