Hi, thank you for your feedback. It turned out to be my own fault, because I had set the parameter unifi.https.port=443 without granting the permission to bind to a privileged port. The IOExceptions are still there but unifi works fine anyway ...

How do you get MongoDB 3.6.x installed on Ubuntu 20.x? MongoDB < 4.x is EOL. Is it just a matter of adding the 3.6 repo?

Hi @USMA56795
If you run apt install --dry-run mongodb-server it will simulate installing mongodb-server and show you the version that would have been installed.
You should find that mongodb-server version 3.6.9 is the current default version for Ubuntu 20.04.3 LTS.

Equally you can check package versions and dependencies with the apt-cache command, as per the examples below.
You will see that the current unifi package has a mongodb-server version dependency of >= 2.4.10 << 4.0.0

uni01:~$ lsb_release -d

uni01:~$ apt-cache policy mongodb-server

Thanks for this! Also- how can I tell which version (unifi version) installed via CLI? (I cant access the webui yet since I need to wait for a pause in production)

Hi @userthirtytwo

Running either of the commands below on the server unifi is installed on should give you the version information.

Version reported by the installed unifi package meta data.

uni01:~$ dpkg -s unifi | grep -i version
Version: 6.4.54-16067-1

Version reported by the running unifi web server API interface.

uni01:~$ curl -ks https://localhost:8443/status | python3 -m json.tool
{
    "meta": {
        "rc": "ok",
        "up": true,
        "server_version": "6.4.54",
        "uuid": "53023d6c-06fd-4ef3-86a5-fad7dafcf280"
    },
    "data": []
}

For those wanting to allow all the ports used by the controller from UI's Documentation, the below adds every port except for the ports used by AP-EDU broadcasting. you might also want to ad an explicit ssh-over-tcp rule with sudo ufw allow 22/tcp.

sudo ufw enable
sudo ufw allow 3478/udp
sudo ufw allow 5514/udp
sudo ufw allow 8080/tcp
sudo ufw allow 8443/tcp
sudo ufw allow 8880/tcp
sudo ufw allow 8843/tcp
sudo ufw allow 6789/tcp
sudo ufw allow 27117/tcp
sudo ufw allow 10001/udp
sudo ufw allow 1900/udp
sudo service unifi restart

For me, this is all that was needed on a clean 20.04 install:

sudo apt-get update
sudo apt-get install --yes ca-certificates apt-transport-https wget

echo 'deb https://www.ui.com/downloads/unifi/debian stable ubiquiti' | sudo tee /etc/apt/sources.list.d/100-ubnt-unifi.list
sudo wget -O /etc/apt/trusted.gpg.d/unifi-repo.gpg https://dl.ui.com/unifi/unifi-repo.gpg

sudo apt update
sudo apt install --yes openjdk-8-jre-headless unifi

Jupp thanks man. This worked flawlessly.

@RocketLR Thanks for these simple instructions. It worked perfectly for me as well. Cheers! 👍

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.
#
# https://gist.github.com/davecoutts
#

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.

@jcgit1

Unfortunately the URL - https://www.ui.com/downloads/unifi/debian is now broken.

I don't have any first-hand knowledge, but it's fair to say that UBNT is no longer interested in maintaining a Linux UniFi download, especially not after their "Dream Machine" and Cloud Key offerings have been available for a while. I had gone through all the hassle and trouble of getting UniFi server working on a local Debian box I have here, but I simply got tired of the constant churn and issues that came up every time they make code changes. So I bit the bullet and bought a Cloud Key Gen2 Plus and it's been working flawlessly ever since. Yeah, it's $200, but it's self-maintained and well worth it. Of course now they're out of stock on it so you'll have to wait until they back-fill, but I highly recommend it.

Hi all, I have had the issue that # apt update gave an error like E: The repository 'https://www.ui.com/downloads/unifi/debian stable InRelease' is not signed. I've tried to add the key, but still had no success. Until I came across this thread.
Because of your comment @davecoutts, I changed /etc/apt/sources.list.d/100-ubnt-unifi.list to: deb https://dl.ui.com/unifi/debian stable ubiquiti and it seems to work. Maybe there was a redirect before, that isn't there anymore? Can someone confirm if this works?

It was likely my bad or bad timing. It looks like https://www.ui.com/downloads/unifi/debian is now forwarded to https://dl.ui.com/unifi/debian/

@davecoutts the issue could be architectures. Looks like the latest stable release dropped ARM support:
N: Skipping acquire of configured file 'ubiquiti/binary-armhf/Packages' as repository 'https://www.ui.com/downloads/unifi/debian stable InRelease' doesn't support architecture 'armhf'

Guessing it's working for you on amd64 or something?

Edit: one can change the release from stable to unifi-7.4 to stick to the explicit release snapshot that still has ARM binaries.

Yes it was the same situation on ubuntu 20.04 64-bit:
N: Skipping acquire of configured file 'ubiquiti/binary-i386/Packages' as repository 'https://www.ui.com/downloads/unifi/debian stable InRelease' doesn't support architecture 'i386'

Fixed it by editing /etc/apt/sources.list.d/100-ubnt-unifi.list file, and defined the architecture:
deb [arch=amd64] https://www.ui.com/downloads/unifi/debian stable ubiquiti

Now the updates are working correctly.
