I remember this being an issue back in 17.10 but I can't seem to find the answer that worked that time.
Basically the indicator that showed the amount of messages on top of the dock icons in Unity is gone (hexchat, skype, etc), and while there's some solutions for Gnome like this Indicator icons do not appear after upgrade to Ubuntu 17.10 or even this https://github.com/electron/electron/issues/9046 (using
export XDG_CURRENT_DESKTOP=Unity in the respective .desktop files), those don't seem to work for Unity or aren't working for this latest version. So far it seems to be the only issue I've found during the transition from 17.10 to 18.04.
What should I try next?
