Hi, I just got a message on my new discourse forum to upgrade to the latest version. On proceeding to the installation (on the black console), i saw some error messages that i dont really remember about an older version. The forum is still up, but when i again try to click “click here to upgrade”, it takes me to the www.website.com/admin/upgrade , which says everything is up to date, but www.website.com/admin still says there are upgrades available. Whats going on? Thanks

I don’t think rebooting is a solution or a recommended action for any problem with Discourse, especially if there’s been a problem with an upgrade. The sensible action here is to move to the Discourse directory cd /var/discourse and rebuild the app from the command line with /launcher rebuild app.

This is from the console that i get when trying to update - An error occurred while installing eventmachine (1.2.0.1), and Bundler cannot continue. Make sure that gem install eventmachine -v '1.2.0.1' succeeds before bundling. Then i did a “apt-get install ruby” (as suggested by my system) - I don’t know why i had to install ruby at this point. Anyway, it went successful. And then when i do - gem install eventmachine -v ‘1.2.0.1’ I get error “Error installing eventmachine. Failed to build gem native extension”

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

Tried, still getting errors… Following is the stuff copied from the command line that opens while updating from the admin panel. *** Please be patient, next steps might take a while *** ******************************************************** $ bundle install --deployment --without test --without development Warning: the running version of Bundler is older than the version that created the lockfile.

Then post-build you can restart them. Failing that if you’re on a virtual machine pay for more RAM.

Good point. I guess take a look at this recent discussion: https://meta.discourse.org/t/memory-useage-tips/44565/3

i use a 2 GB RAM server…and i have almost 1 GB free… pretty sure that is free enough. Any other ideas?

If you read the link above, then visit the swap-file page you’ll see this: We recommend a 2GB swap file for Discourse, unless your server has 4GB or more of memory. I think that means that you should add the swap file and/or upgrade your RAM.

i see.. i’ll check that now. Thanks

I had this exact issue - Discourse on DO with 2GB RAM and no swap worked fine, except for updating from the Discourse dashboard. So I would always rebuild the app via SSH instead. Adding 1GB swap file fixed it for me; updating from the dashboard now works.

Or add a swap file or increase the size of your swap file.
