The first time I tried to run the migration failed with the warnings:
```auto
+ discourse-ynh-deps : Depends: postgresql but it is not going to be installed
+ Depends: postgresql-server-dev-all but it is not going to be installed
+ Depends: postgresql-contrib but it is not going to be installed
+ synapse-ynh-deps : Depends: postgresql but it is not going to be installed
```
I wasn’t really using discourse or synapse, so I continued by uninstalling discourse and synapse through yunohost, and then running in terminal:
```auto
apt-get remove discourse-ynh-deps
apt-get remove synapse-ynh-deps
```
I then re-ran the migration, and it worked successfully.
Sharing here, in case anyone runs into the same issue.

Ugh yeah that may somehwat work, but this is not recommended because after this, `apt autoremove` may want to uninstall a bunch of dependencies that are required for discourse and synapse to work … Unless you follow this up by a forced-upgrade for both apps
