Description

The CRS team believes that strange CRS problems are reported when users use NGINX Ondrej PPA.

Reports:

  • SO link to follow FIXME

What we think the problem is: FIXME

We would like to solve this problem (if any) or have it documented so users understand how to follow.

Statements from chat so that we don't lose them:

  • We believe that the Ondrej PPA is responsible for the very strange errors we've seen reported over the past 2 years. E.g. "200 is not a number" and very odd things like that. (bearbeitet) (LINK?)
    We've had, I think, 4 separate reports.
  • Yes, I think one remembers issues with that PPA and some bad dependencies. (LINK)
  • yeah, there were some PCRE issue (LINK)
  • Ondrey likes to use his own PCRE package (because of the PHP) (clarified the why below)
