Hello. After updating to 0.9.11, 1password would no longer launch using the shortcut in the applications menu. After running
/opt/1Password/1password manually, I received this error:
[2168:0203/130347.498777:FATAL:setuid_sandbox_host.cc(158)] The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I'm aborting now. You need to make sure that /opt/1Password/chrome-sandbox is owned by root and has mode 4755. Trace/breakpoint trap
Correcting the permissions on chrome-sandbox from this:
-rwxr-xr-x 1 root root 4.6M Feb 1 11:06 chrome-sandbox
-rwsr-xr-x 1 root root 4.6M Feb 1 11:06 chrome-sandbox
(as the error describes) fixed the issue. But, I thought it would be worth mentioning/reporting here, in case anyone else runs into it. If it helps with debugging, 1Password was "closed" but running in the background when it was updated.
