I upgraded my xubuntu 18.04 to 18.10 and then right away to 19.04 2 days ago. After this, Flash player on Firefox works, but on not Chromium and all derivates like Opera, Chrome, etc. I tried to reinstall them all, did all the workarounds that Google and Adobe say on troubleshooting help sites, tried to install and uninstall different packages through Synaptic package manager, clean caches, but no success. I installed a snap version of Chromium from command line, and that one says "plug in not supported", the others are on a permission looping without displaying content. In some time i will o a fresh install of 19.04, because maybe it can be related to installation errors or Kernel version???? TX!
