Hello, I am hoping to get some help with this. I am attempting to install the Kolab Calendar plugin. I am following the install instructions found at git.kolab.org/diffusion/RPK/browse/master/plugins/calendar/ . When I get to step 4 "Build css styles for the Elastic skin $ lessc --relative-urls -x plugins/libkolab/skins/elastic/libkolab.less > plugins/libkolab/skins/elastic/libkolab.min.css"" I receive the following error in my terminal "bash: lessc: command not found" I was wondering if anyone had any ideas, or better yet, successfully installed the Kolab Calendar Plugin on Debain with ISPConfig 3.
You need to install lessc; exactly how depends on what OS you have, but a quick web search should tell you.
On a Debian 10 system I had quite a bit of difficulty getting this to work, but I did end up getting it. The specific package I needed to install was node-less. Hope this helps someone in the future. Also Kolab's install instructions aren't the best, that's for sure.
