Synapse Installation fails during build of wheel lxml

Hello everyone,

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:
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

Here’s the complete log:
Any ideas?

And in particular :

/usr/bin/ld: cannot find -lz`
Which is uuuugh cryptic

But can you try to sudo apt-get install zlib1g-dev

and see if that fixes the issue ?

Installation succeeded, thank you very much. Now I only have to fix some port problems.
