Smarty fails with The e modifier is no longer supported

[solsson]

Got this from the details page upon fresh docker-compose up:

Warning: preg_replace(): The /e modifier is no longer supported, use preg_replace_callback instead in /opt/rweb/repos-web/lib/smarty/libs/Smarty_Compiler.class.php on line 269

Oddly after reload the page is white.

At a fresh install, with docker-compose running on ubuntu:

Smarty is installing...

Fatal error: Can not write to this lib's folder. in /opt/rweb/repos-web/lib/uncompress.php on line 20

Actually I suspect something with the docker-compose run is pretty flawed. Logs say
