Something seems to have gone wrong with my update

(Peter N Lewis) #1

Something seems to have failed with my update to 1.7.x (

Nothing is showing up and I’m getting errors like:

I’m wondering if the update failed part way through.

Any suggestions on how to get it going again?

Have you tried safe mode? Any incompatible plugins can break you.

(Peter N Lewis) #3

No safe-mode does not do any better. It asks me if I want safe mode and I say yes I still get the same result. Nothing shows up at all

(Jeff Atwood) #4

Try rebuilding again from the command line. If you are using any third party plugins, remove them before rebuilding.

(Peter N Lewis) #5

Would that be:

cd /var/discourse
./launcher rebuild app

Will that update any files if they are not up to date?

(Jeff Atwood) #6

Yes, give that a shot, but be sure to remove any third party plugins from the app.yml first.

I disabled solved and tags

#          - git clone
#          - git clone

but I get this error when rebuilding:

That’s odd. Tagging has been in Discourse as a core feature for a few versions now.

Make sure you add a git pull in there if you were on a very old version:

cd /var/discourse
git pull
./launcher rebuild app

(Peter N Lewis) #9

I was on 1.6.x (the latest before 1.7 I believe).

I’ll try.

root@forum:/var/discourse# git pull

Should I enter the docker container and then try:

apt-get update


(Peter N Lewis) #12

What is supposed to be going on with postgresql?

The error reports

The following packages will be REMOVED:
  postgresql-9.5 postgresql-client-9.5 postgresql-contrib-9.5

But if I do apt-get update to see what it wants to do, it wants to install postgresql-9.3 postgresql-client-9.3 postgresql-contrib-9.3

So which version is supposed to be installed? Why would 9.5 be installed already and why would it want to remove it when upgrade wants to install 9.3?

(Jeff Atwood) #13

We updated our docker image to Postgres 9.5 back in May 2016

(Peter N Lewis) #14

OK, my app.xml was still saying postgres 5.3. I changed it to just postgres and the rebuild worked and I am back up and running.

Thanks for your assistance!

Now I should be able to reenable the solved plugin.

I presumably don’t need to reenable the tags plugin as you say.
