Using Ubuntu 20.04.3 lts.
In ubuntu software, I only show 1 icon for opera, but in apps menu, 9dots, I see 2 opera icons. i can open both at same time. One says ver 80... for core 18, and 2nd icon shows ver 68... core 20.04.3.
How to uninstall core 18 version only? under opera help, about, the install says: /snap/opera/145/usr/lib/x86_64-linux-gnu/opera (ver 80)
and: /usr/lib/x86_64-linux-gnu/opera (ver 68)
