I want to install MongoDB 3.6.5 in my ubuntu machine.
Please share any link as i am unable to install it from mongodb official site even by mentioning the version in the command.
Try this link
https://www.mongodb.com/download-center/enterprise/releases/archive (Search for 3.6.5, there a few Ubuntu Flavors there)
It looks like because its an older release its not listed in the main download link (closest I could find there was 3.6.8) for MongoDB Enterprise Server
