When running ./launcher rebuild app, I got this error. Nothing fancy, just a regular install. FAILED -------------------- Pups::ExecError: cd /var/www/discourse && su discourse -c 'SKIP_EMBER_CLI_COMPILE=1 bundle exec rake themes:update assets:precompile' failed with return #<Process::Status: pid 1…

AI suggested I add DONT_PRECOMPILE_CSS: 1 to my app.yml, which worked.

I wonder, would setting my version to stable help?

EDIT: Will try that as soon as I can.
