Thank you for you bug report, it seems likely to have to do with the
content of ~/.ssh/known_hosts , does it stop if you move that file away?
If so could you try to figure what line is creating the issue and share
it (or at least describe what it looks like even if you replace
names/keys)

Title:
ipset bash auto complete error on ubuntu 18.04
Status in ipset package in Ubuntu:
Incomplete
Bug description:
I have tested it on a brand new Ubuntu 18.04 amd64 system, then install the ipset package
when I type "ipset " and press tab to trigger bash auto completion,
it returns "-bash: syntax error near unexpected token `;;'".
ipset version: ipset v6.34, protocol version: 6
here is the full log, and I can see it fail when excuting eval
