ERROR: Docker version 1.9.1 not supported, please upgrade to at least 17.03.1, or recommended 17.06.2

I’m trying to run ./launcher rebuild app on my app, but everytime I do, I get this error:

ERROR: Docker version 1.9.1 not supported, please upgrade to at least 17.03.1, or recommended 17.06.2

Can someone point me in the right direction for updating docker please?

I’ve tried sudo apt-get update and sudo apt-get upgrade.

Thank you.

If yo search for “docker version not supported” you’ll find Docker version not supported after the later update.

From experience: Even if you master the docker-upgrade, you may then strand in some discourse-db-update issues, leaving you with a broken system.

My recommended solution would be: Take a backup (before anything else, make a download…). Attempt docker upgrade, and if this fails, make a fresh install, reinstall from backup.

In plus check for images “missing” (rsync between old and and installation in terms of uploades images.)

My apologies, I did do a search, but that particular answer evaded me.

I’ve followed the instructions in that other post, and have gotten the following:

I have taken a backup of the app as it stands right now, so I could just go ahead and try it any way - but I’m not sure I trust it’ll work, and don’t want to have to re-provision the server right now. I fear I may be stuck on the current version of discourse for a while.

Sorry. That’s not the message that I remember seeing, but you’re going to build a new image anyway, so you should be safe.

If you have a current backup, worst case you can wipe the system, do a clean install, and restore the backup.
