I'm running wireshark 3.6.2, --and it's really stable, --I'm also running more than one 4.x, --and at the moment 4.4 is really beating me up badly, --bugs, -crashes when I start a trace, --don't want to beta test, -I want to put everything back to version 3.6.2 or something stable in Ubuntu.
How do I downgrade Wireshark in Ubuntu?
