seems it is stucked with previous install or something, I do not know howto proceed.

UPDATE: if I try to do a clean install also fails, it looks like it has some pending/hanging apps

yunohost app install synapse
Choose the domain where this app should be installed [domain.tdl | matrix.domain.tdl]: matrix.domain.tdl
If your Synapse domain is a subdomain, you can choose a name for your Synapse server to have your Matrix user-ids looking like @user:domain.org instead of @user:synapse.domain.org: domain.tdl
Is it a server with free registration? [yes | no]: no
Jitsi server address for conferencing?: jitsi.riot.im

then again, it seems that @SIM have already run into this issue and was solved as he explains here:

https://forum.yunohost.org/t/solved-solution-synapse-upgrade-from-1-38-to-1-42-failed-backup-restore-failed-too/17406/4

it is about hanging permissions.

so to solve i did:

• yunohost app remove synapse as it did have errors installing
• runned yunohost tools shell -c "from yunohost.permission import permission_delete; permission_delete('synapse.main', force=True)" yunohost tools shell -c "from yunohost.permission import permission_delete; permission_delete('synapse.server_api', force=True)" yunohost tools shell -c "from yunohost.permission import permission_delete; permission_delete('synapse.server_client_infos', force=True)"
  • recovered the backup yunohost backup restore synapse-pre-upgrade1
