On the forum I use as a test bed, I just did some normal maintenance routines, and now I get this error during a rebuild Removing old container + /usr/bin/docker rm app Error response from daemon: Driver aufs failed to remove root filesystem b610111d39e8634398cd28b510bf362b09640e9111438503c12d22b3c…

I ran discourse just fine on 14.04…i’m confused Have you done: sudo apt-get install \ linux-image-extra-$(uname -r) \ linux-image-extra-virtual from the installation guide ?

Why not use a 16.04 image? Also you could give the output of uname -r – which would be immensely helpful here but I’d recommend just updating to 16.04 unless you have a reason to be on 14.04

This has been 14.04 since I installed it a while back.. I could upgrade to 16, but will that stop the mysterious aufs issues which have come up from time to time?

Well then… that’s reason enough to upgrade to ubuntu 16 :heart: After the latest apt-get upgrade, the right 3.13.0-71 image-extra package was missing, hence the aufs error. The command you linked to solved it for now, I’ll be making backups of all my discourse hosts & upgrading.

You don’t need to upgrade now…you won’t have an issue…but you REALLY should at some point :slight_smile:

Upgrade now, when I’m ready for issues? Or when some random apt-get upgrade will stop the show? Hahaha, thanks, this is plenty reason to start the process of upgrading.

This has always been an odd problem to me since the official install guide says to use the wget command from get.docker.com to install Docker. And I have never observed this problem on any install we did, which obviously follows the official guide slavishly. wget -qO- https://get.docker.com/ | sh S…

I dunno about the docker aspect.. this instance has been running fine for over a year, through other docker upgrades even. Today I did apt-get upgrade and I got fussed at about a lack of aufs. I don’t even think it was a docker issue, but a mismatch of kernel & image-extra. If ubuntu 16 resolves t…

Yup, it certainly will! I’ve been sysadmin for two discourse installs, so can vouch for it not sucking. Just ensure you follow the docker install instructions.
