Doesn't work on Ubuntu 18.04

[mxssl]

Hello!

I checked on several ubuntu 18.04 machines and a problem looks similar - process-exporter cannot read processes from /proc directory. This counter shows it:

namedprocess_scrape_procread_errors 121

About OS and configs:
/etc/os-release

On ubuntu 16.04 machines process-exporter works as expected.

Thanks for the bug report. What version of process-exporter are you using? Version 0.3.1+ contain a lot of new changes and should have been labelled pre-release (they are now). If you haven't already, could you try with v0.2.12 and let me know if you have any better results?

Yes, I tried version 0.3.1

0.2.12 is working fine on ubuntu 18.04, thank you.
