greenlight: docker error "failed to create shim task: OCI runtime create failed"

[Thomas Müller]

Hi,

when updating BBB to 2.5.12 from 2.5.11 using script "https://ubuntu.bigbluebutton.org/bbb-install-2.5.sh" I got an error:

v2: Pulling from bigbluebutton/greenlight
Digest: sha256:ea1ca8257f484e3c76310ffe273ce3c223627605b6f52ea04f0a3606a319a4fe

ERROR: Encountered errors while bringing up the project.

So Greenlight doesn't start anymore.

Any idea how to resolve this issue?

System is a clean installed Ubuntu 20.04 at the time BBB 2.5 was published. Install and update runs using the script as root:

wget -qO- https://ubuntu.bigbluebutton.org/bbb-install-2.5.sh | bash -s -- -w -v focal-250 -s bbb1.<DOMAIN>.de -e bbb@<DOMAIN>.de -g

Regards

Update: it sems to be related to the Docker update to 23.0.1 (regular ubuntu updates uing apt upgrade) and occurs even on a fresh installation of BBB 2.5 on Ubuntu 20.04.3, at least when running BBB install script after applying all Ubuntu updates before installation. 

After reverting docker-ce back to 20.10.23 (using "sudo apt-get install -y docker-ce=5:20.10.23~3-0~ubuntu-focal") the install script finishes and greenlight works again (even while the bbb install script seems to upgrade docker to 23.0.1 again).

I also have to downgrade. BTW: Correct command is

apt-get install -y --allow-downgrades docker-ce=5:20.10.23~3-0~ubuntu-focal

Maybe a solution is the Installation of  recommend package apparmor....

Hi Thomas,

I've had the same problem and resolved it by installing apparmor by running

sudo apt-get install apparmor

Hi all,

Same issue here, when tried to upgrade BBB from 2.5.11 to 2.5.12.

Already tried to revert back the docker version and still did not work. Then I tried to run the install script again and since it updated docker again... same error.

Also tryied to run the commands after installation:
cd greenlight
docker-compose down
docker-compose up -d
bbb-conf --restart

Still Greenlight does not work. It gives "502 Bad Gateway nginx". BBB is working fine, just tested with my Moodle.

Did not tried to mess or install apparmor, since for now I want to avoid enable it. So anyone has as solution for this?

Thanks

Did you downgrade docker-ce?

Can you show us

apt info docker-ce

Hi Max,

I've tried it too, but it didn't help in my case (I think it was already installed, because while dealing with the problem I removed it before - as far as I remember). 
Only downgrading docker-ce to 20.x (by removing and installing in two steps or with "--allow-downgrade" option as single step) solved it on 2.5.12 (production) and 2.6-rc... (experimental).

Btw: running the official bbb install script after this replaces docker-ce 20.x with 23.0.1 again, but this time it doesn't make any problems...

Regards,

Thomas

Had the same issue (on two boxes, another two were fine).

Apparently it depends on the base image you used, had to manually

sudo apt install apparmor && reboot

to fix it.
