IndexError: list index out of range in assign_networks_by_default

[Gleb]

I can't assign role to the nodes.

After Fuel installation I run bootstrap_admin_node.sh few times to change admin network interface and ntp servers.
The nodes were discovered but I can't assign roles to them.

Please see atached logs for details.

try

/opt/nailgun/bin/manage.py dropdb
/opt/nailgun/bin/manage.py syncdb
/opt/nailgun/bin/manage.py loaddefault

this will purge and reset your db

It seems that the node with id=39 wasn't mentioned previously (for 28 hours at least).
Did you use UI?
What is the Fuel version or commits?

Andrew Woodward's solution works! Thanks a lot, Andrew

An user reproduced this error while upgrading from 5.0.1 to 5.1.
Then, creating a new env got stuck

Cleaning the db with the Andrew suggestion worked fine though:

dockerctl shell nailgun
manage.py dropdb
manage.py syncdb
manage.py loaddefault
