I just finished updating my zammad instance, no issue at all. I’m using the source installation on ubuntu-18.04.
Near the end, I’ve seen these warnings:
... Bundle complete! 99 Gemfile dependencies, 141 gems now installed. Gems in the groups test, development and postgres were not installed. Use `bundle info [gemname]` to see where a bundled gem is installed. Post-install message from i18n: HEADS UP! i18n 1.1 changed fallbacks to exclude default locale. But that may break your application. Please check your Rails app for 'config.i18n.fallbacks = true'. If you're using I18n (>= 1.1.0) and Rails (< 5.2.2), this should be 'config.i18n.fallbacks = [I18n.default_locale]'. If not, fallbacks will be broken in your app by I18n 1.1.x. For more info see: https://github.com/svenfuchs/i18n/releases/tag/v1.1.0 Post-install message from icalendar: ActiveSupport is required for TimeWithZone support, but not required for general use.
I ignored them and everything seems to work well. Do you propose any action?
Thanks for your work and support, Uli
