I recently installed Ubuntu 19.04 from 16.04 and I was happy with how quickly Ubuntu evolved over the years.
Since I use Notion a lot, I quickly realised the emojis are not showing properly on chrome.
Turns out the problem was ubuntu’s minimal install which did not include the emojis package as discussed here. https://discourse.ubuntu.com/t/emoji-support-missing-from-ubuntu-19-04-minimal-install/11083
So I went ahead and installed “fonts-noto-color-emoji” package using
sudo apt-get install fonts-noto-color-emoji
My terminal now says, the package is already installed, which was strange, maybe they added the package but there was no change.
On further research, I found I had to remove and install it again as suggested here. https://askubuntu.com/a/1196561
sudo apt-get remove fonts-noto-color-emoji
sudo apt-get install fonts-noto-color-emoji
Then restart Chrome, and you will get all the fancy emojis you need. :)
