Comment 1 for bug 2060449

This only happens if you were running 7f700c4d79d2a39bb527d4c1161d5e6e329555c7, before 2177bbe0fb2fea7d114e0099496380f3c41702fa. The former created CA certificates that couldn't be used by the Temporal SDK.

2177bbe0fb2fea7d114e0099496380f3c41702fa fixed the issue, so anyone using released version of MAAS wouldn't run into this.

For development instances, the following can be done to fix the issue:

sudo snap stop maas
sudo rm /var/snap/maas/current/certificates/*
sudo -u postgres psql -d maasdb -c "delete from maasserver_secret where path='global/maas-ca-certificate' OR path='global/cluster-certificate';"
sudo snap restart maas
