snap chromium won't start on Ubuntu 14.04

Asked by Toshi on 2020-07-24

Hello guys, can anyone give me advice?
I'm a newbee to snap command.
I have tried to use snap chromium(channel=candidate/vaapi) but failed.
Error messages I got are here;

toshiomi@toshiomi-Inspiron-1210:~$ snap run chromium
Failed to move to new namespace: PID namespaces supported, Network namespace supported, but failed: errno = Operation not permitted
Trace/breakpoint trap (core dumped)
toshiomi@toshiomi-Inspiron-1210:~$ snap run chromium --no-sandbox
[6015:6015:0725/] Unable to open X display.
Something goes wrong, but no idea how to dig this problem...
DEB version chromium-browser and other X commands work well.

Info of my box is here, (uname -a; snap list --all; snap info chromium)

Support for Ubuntu 14.04 has already ended a year ago (except for ESM which is a paid option for security updates for selected server packages), see

And for your error message:
A web search lists
Maybe that helps.

Thanks for your replies.
Finally I have found it works on 16.04 LTS. ;-)
