• Check if mongo services still running, there are some:

root@giverny:~# date; ps aux | grep mongo
Thu Nov 18 09:19:20 CET 2021
grouss    3578 64.1  6.9 33059300 11395928 ?

• @grouss stopped the services in question

• Then the actual upgrade (roughly):

root@giverny $ apt upgrade -y
root@giverny $ reboot
root@giverny $ # Update sources.list references to buster
root@giverny $ sed -i s's/stretch/buster/g' /etc/apt/sources.list.d/*.list
root@giverny $ apt upgrade
root@giverny $ apt dist-upgrade
root@giverny $ reboot

And now giverny seems to refuse to boot back. Stopping a bit that part as I cannot check further yet. I'll check the desktop machine physically tomorrow.

Mounting volumes was the root cause. After fixing those in fstab, giverny boots back. It's now in buster.

And i'll stop at buster in the end.
