Setup the server myself so it is very possible there are some missing pieces on my end. But I have Ubuntu, PHP, PGSQL, APACHE2 all installed and working. I go to Extenstions -> Install from package -> Upload 001_pkg_communitybuilder_2.4.6+build.2020.08.25.20.48.37.dd91ffef7.zip and it reports Failed. When I look at the logs it give me
001_pkg_communitybuilder_2.4.6+build.2020.08.25.20.48.37.dd91ffef7.zip is being installed.
001_pkg_communitybuilder_2.4.6+build.2020.08.25.20.48.37.dd91ffef7.zip failed to install! hide
