##  Previous install steps from when unifi still required mongodb-server <= 3.4.
##  unifi has since been updated to work with mongodb-server 3.6. Which is available from the Ubuntu 20.04 main repository.

Yes, thank you for this! I love Debian, but I wasted over an hour fighting with Debian 11 and mongodb versions and other apt problems; I lost. This just works, I installed at Unifi version 7.1.66. I spun up an Ubuntu 20.04 Linux container in Proxmox, updated and (since I was logged in as root, removed sudo, and I like to type Y so):

apt-get install ca-certificates apt-transport-https wget

echo 'deb https://www.ui.com/downloads/unifi/debian stable ubiquiti' | tee /etc/apt/sources.list.d/100-ubnt-unifi.list

wget -O /etc/apt/trusted.gpg.d/unifi-repo.gpg https://dl.ui.com/unifi/unifi-repo.gpg

apt update

apt install openjdk-8-jre-headless unifi

Thanks Dave and everyone.

@lamixer you are welcome.

I feel your dependency hell pain.

The software stack versions for unifi are starting to become a problem with newer operating systems.
The issues I have found are,

• mongodb has been dropped from the stable Debian and Ubuntu repositories.
• unifi requires mongodb 3.x, which requires libssl1.1, which Ubuntu 22.04 depreciated in favor of libssl3.
• Debian stable has dropped openjdk 8. unifi dependencies states it can use openjdk 11. Yet unifi fails to run without modifying the openjdk 11 installation.

I do hope Ubiquity is planning to update unifi to make it easier to install on current Linux operating systems.

If you would like to try Debian again I found that the following install steps worked on Debian 10 and 11.

# unifi 7 Debian 10 & 11 installation.

# Install and enable mongodb 3.6

sudo apt install --yes mongodb-org-server

sudo systemctl enable mongod.service
sudo systemctl start mongod.service

# Install unifi

sudo apt install --yes unifi
sudo apt clean

# Post installation checks

All - thank you for all the comments and discussion here.

With this post and some extra work, I was able to get Unifi working on Ubuntu Jammy on a Raspberry Pi arm64. Especially thanks to @dbosk for pointing to the armhf Unifi repo.

I wrote up a description and ansible role for those wanting a script and explainer of what worked for me.

what is default admin username and password of mongodb ?

Off the back of @ficematt using https://glennr.nl/s/unifi-network-controller make the process alot easier 👍
