Hi! I just installed a forum on an ubuntu 16.04 linode instance using docker instructions. I also created an instance on a local VM so I could import my old smf2 based forum to it. Once imported I created a backup in the local VM through the discourse backup tab. I then applied this backup onto my linode instance following these instructions: > [@Is there any way to restore your site from backup in the terminal?](https://meta.discourse.org/t/is-there-any-way-to-restore-your-site-from-backup-in-the-terminal/42377/9): > > It worked for me by first getting into the app ./launcher enter app then discourse enable\_restore discourse restore \ discourse disable\_restore Using the script/discourse didn’t work Everything seems to work fine except the version check in the admin dashboard: “A check for updates has not been performed. Ensure sidekiq is running.” I’m using the latest release of discourse (as of this post discourse (c5f42f0) ) and HTTPS is enabled. Sidekiq is running and actually has a few retry jobs all with: > ` Jobs::HandledExceptionWrapper: Wrapped JSON::ParserError: 743: unexpected token at ' Discourse 7:15 pm > Job exception: 743: unexpected token at ' > > Discourse > > ``` > ``` > > > > > ``` > ``` > >

Any ideas how I could resolve this? I’ve already rebooted the node and ./launch rebuild app with no effect. --- _[View the full topic](https://meta.discourse.org/t/json-parsererror-on-jobs-versioncheck/64650)._
