What linux OS is supported?

[Oren Yehezkely]

Hello,

I need to install some of your servers. I could not find any indications which Linux OS flavors do you support.

This is very confusing.

Thanks!

There's hundreds, if not thousands of Linux distributions.  Atlassian don't refuse to support any of them, but instead give you a general guide to what they are willing to support or help with - see https://confluence.atlassian.com/adminjiraserver072/supported-platforms-828787550.html (yes, that's for JIRA, but the Confluence page just says "Linux".  This goes into better detail)
