##  unifi has since been updated to work with mongodb-server 3.6. Which is available from the Ubuntu 20.04 main repository.

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 @jcgit1

I'm not seeing an issue with the unifi repository located at https://www.ui.com/downloads/unifi/debian

What do you see when you attempt an install or update using that repository?

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.

I have tested the code that I have published in my git repository below and works fine for me.
