I did a new install this month based on Armbian. After installing nextcloud, I tried Synapse as my second app.
My YunoHost server
Hardware: Rock64 at home
YunoHost version: 220.127.116.11
I have access to my server : through the webadmin and if required direct access via keyboard / screen
Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : new install, IPp6 and email not yet working.
Description of my issue
I tried to install Synapse. It failed with the error
Failed building wheel for lxml
