Apps Stuck Updating - Cleaning up old install - even after stopping/restarting task

[girish]

@humptydumpty yeah, I think what has happenned is that the docker is getting stuck again and thus addon containers are not getting created properly. Can you give me SSH access and drop a mail to support@ ? I can try to see if recreating the docker images solves anything.

[humptydumpty]

@girish email sent .. btw should I close the addon container putty window?

[girish]

@humptydumpty thanks, just looking into this now. Indeed:

2022-11-22T05:48:22.494Z box:shell removeAllContainers exec: docker ps -qa --filter 'label=isCloudronManaged' | xargs --no-run-if-empty docker stop

docker is not responding So, I will recreate the docker images completely . I did this now on @jdaviescoates ' server a while ago to see if it helps as well.

Further, I am unable to remove the docker directory even after stopping and disabling docker...

Some dangling container is causing problems:

I guess this is why it's hanging, it's unable to remove images.

@girish what are my options to get the server back up? snapshot restore? dashboard is up! apps are in "configuring - queued" state.

[girish]

@humptydumpty yes, I just removed the entire /var/lib/docker and re-creating all the apps (had to reboot to even remove it since it was locked by various processes).

[humptydumpty]

@girish they're "configuring" now. thanks!

[humptydumpty]

@girish excluding the time to install ubuntu which was around 10 mins at most, do you think i missed any incoming mail during the addon container recreation time?

[girish]

@humptydumpty practically, all email servers will retry sending email if they caught you in the downtime.

Well, something is different. I see in your email that an n8n update successfully worked after the changes you made, but I just tried updating the outstanding WordPress update...

Now just seemingly stuck here:

So I tried clicking Restart App, which didn't work, so I tried Retry Task, Retry app restart, which did work but of course the app still isn't updated, but back where it was before I tried to update.

So, tried to update again, exact same thing. Just stuck on "Updating".

Sigh. I'm beginning to regret my server move (not only because of this, but also because I've been hitting email issues too - in part because my new IP was/ is blacklisted, but also because email keeps timing out which never used to happen before either)

Adding log:

All I could see when it first got stuck on "Updating" was this:

Nov 22 14:02:09 [POST] /backup
Nov 22 14:02:09 backing up
Nov 22 14:02:09 13:M 22 Nov 2022 14:02:09.480 * DB saved on disk

[girish]

@jdaviescoates I think this is something else, maybe I forgot something, let me check.

[jdaviescoates]

Then the restart, retry, attempt to update again logs (too long to paste here):

[girish]

@jdaviescoates this was a bug with the patch I made yesterday to use docker cli instead of the docker API. I will revert back the code on your server to use the API.

[humptydumpty]

@girish do you still need SSH access for further investigation?

[girish]

@jdaviescoates reverted now.

[girish]

@humptydumpty done, thanks for the access. Let me know after a few updates how things are working out.

Thanks, tried again but:

[girish]

@jdaviescoates Yeah, ok, I am out of ideas then.

Just tried a simple example:

[girish]

@jdaviescoates I don't know how motivated you are to track this down, but either you can ask them for another server? I have the VPS 500 G10s iv in netcup .

Another idea is to go back to plain ubuntu and try to reproduce this issue with just docker since it's not Cloudron related. But not sure what you will gain with this...
