Wekan fails to install with `error code 1 and signal null`

ctrl

Hello Team,

we just tried to install Wekan for a couple of times. But each attempt quits with error code 1 and signal null. I watched the logs during the installation process and I assume something unexpected happens during the extraction process. The last entry I see is:

Oct 28 14:03:11 box:docker pullImage: {"status":"Extracting","progressDetail":{"current":75202560,"total":310999233},"progress":"[============> ] 75.2MB/311MB","id":"09a34c31c952"}

Currently and according to df and docker system df there seems to be free space of ~2.8G. Is it too less for Wekan? For testing purposes I tried to install other apps without any issues.

Can you check the system logs (you find them in the top right of the system view in your Cloudron dashboard). If the task crashes for some reason it might get logged there.
Next release it will be part of the actual app task logs again.

This one looks quite suspicious:

Ok so the app task did indeed crash. Now hopefully we can find that crash in journalctl --system somewhere

Sorry that since some Cloudron releases the crash logs are a bit all over the place until the next.

The other issue is interesting, but I don't think related. Is is possible that some non admin user has the dashboard open? Maybe there is a bug where it tries to show progress?

Do you have any keyword in mind? ^^ box-task-4772 maybe?

No, we just double checked. I'm the only user being logged in currently.

These entries correspond to the time of the last installation process.

nebulon

The task id might not be there, maybe try to match the timestamps or run journalctl -f --system as root while retrying the installation.

nebulon

Hm ok, this does not reveal much. Maybe it is the issue of running low on disk space. Docker images tend to be quite large and wekan is meteor which pulls in a lot of stuff. Can you see anything in the journalctl -u docker logs?

@nebulon
I just let the installation run again while watching the live journal.

EDIT:
For testing purposes I could move the docker images onto an external volume tomorrow and report back afterwards.
Could you please confirm if this guide is still valid?

nebulon

Yes those docs are still valid and is a good idea here for testing.

girish

Out of curiosity, does this happen with other apps as well or just Wekan? The "Not continuing with pull after..." implies some docker error. Does docker pull cloudron/io.wekan.cloudronapp:20201021-004852-015f556b1 work on the server ?

ctrl

@girish
There were no issues installing other apps inbetween.
I just did a manual pull on the shell as you proposed:

Looks like the available space is not sufficient. But as I said earlier, not even ~2.8G seem to be enough. Do you have an estimate how much it requires approx.?

nebulon

I think wekan is really some outlier here, we may have to improve the package for it to consume less space, but I am just preparing a new wekan release and saw that there were at least two layers one 1Gb and another close to 3Gb for that image!

ctrl

@nebulon
Ok I see. Thank you very much for the clarification! ^^
I'm going to move the image location to an external volume for the time being.

It looks like the last docker pull command of the previous test ate some space. Could you guys please tell me how I would clean up the remaining cruft?

EDIT:
Reporting back that it was installed successfully after changing the image location to an external volume offering enough disk space.
