Hi folks,
I’m a bit new to Nextcloud and running some tests. My install is running on the VM from Hansson IT. I’m trying to install the Face Recognition app, and getting the message below. Any ideas on how to resolve this?
An error occured during the request. Unable to proceed.
App “Face Recognition” cannot be installed because the following dependencies are not fulfilled: The library pdlib is not available.
If something is missing, you need to install it 
Install and activate the php7.x-pdlib module on your server which should also install the underlying pdlib library itself.
Ok, I guess I really need to spend some time learning Linux better. I’m in the process of migrating off Big Tech, so, no more MS Windows. I’ll have to research how to install pdlib.
Hi @DadOfRCA,
If your VM is running Ubuntu focal (20.04), those instructions should work for you:
I hope it helps!
Thank you.
Yes, this helps. I’ll play around with this.
I’m having the same issue but now I’m getting “permission denied” when I go to run:
`echo "deb https://repo.delellis.com.ar focal focal" > /etc/apt/sources.list.d/20-pdlib.list`
I downloaded the VM from https://www.hanssonit.se/nextcloud-vm and imported into VMWare. I ran the first setup menu and have NextCloud running but can’t install App “Face Recognition because of this error.
Hey @GetCart3r if you are still on NC20, you can try this script which should make the whole install process much easier 
THanks for the quick reply @szaimen
Sadly this is where my coding/Linux experience is lacking. I went to the link but now sure what I need to do.
Also this issue is on both a dedicated laptop that’s running NextCloud and the VM that I downloaded today. Laptop is v.21 and I thought the VM was21 after updates.
Unfortunately, the facerecognition app isn’t compatible with NC21, yet. So the installation of the app will fail.
If you still had NC20 installed, it would be a simple:
wget https://raw.githubusercontent.com/nextcloud/vm/enh/facerecognition/apps/face-recognition.sh
sudo bash face-recognition.sh
Ahh ok thanks! So the latest VM must also be 21. I will see about downloading an older VM with 20 and give it a try.
I’m now at a total loss. I’m running version 20 VM and still when I run either of the commands all I get is "permission denied”
Which commands did you run?
Thanks @szaimen finally got it installed. I was getting errors but then selected to uninstall Face Recognition then reinstall and that cleaned it up.
Not sure how long it will take but will see what happens over night.
Thanks!
Hi all,
After tinkering around for 7 days to make my nextcloud instance working with Face Recognition and Memories, finally I make it, just want to share my configuration here
It is newest nextcloud (nextcloud 16) and I’m using docker with pdlib and hardware acceleration working. (i5 7600 without any vga card)
Docker compose

Install your nextcloud first, and add Face recognition apps and Memories (optional)
for post installation, go inside the container
docker exec -it nextcloud bash
Run the start.sh

configure Face Recoginition memory
sudo -u www-data php occ face:setup --memory 10GB

to verify if you have qsv (QuickSync Video), run this command, and verify if you have h.264_qsv, h.265_qsv, etc working
ffmpeg -decoders | grep qsv
ffmpeg -encoders | grep qsv
And then restart your container
docker-compose restart nextcloud
I hope this helps everyone who wants to create their own nextcloud with face recognition.
