SMIME Internal Server Error on Certificate Verify

mcostan

Good morning,

I am having a similar problem. When I open an encrypted email I get an error and in the log file I can see this:

Mon Jul 01 14:18:05.950394 2019] [:error] [pid 9089] [client 127.0.0.1:43534] PHP Fatal error: Uncaught Error: Call

What do I need to do?

Could you share information about your setup?
OS, php version, WebApp version etc

@marty

WebApp:
3.5.8.2339+1314.1
Kopano Core:
8.6.9
Z-Push:
2.5.0+0-0

And the latest version of the S/MIME plugin downloaded from the community site yesterday.

@yep_DD
I am having exactly the same problem

gabriele

Note that I am able to view the email from my mobile phone and also if I forward it.

@marty

I was wondering if you need any further information or log files for this.

marty

By the look at the error it seems you’re missing php-bcmath (or it’s not active)

mcostan

@marty

Marty that fixed my problem! Thanks a lot!!

Question: should that package be in some dependencies? For example of the S/MIME plugin?

Otherwise how do people know that they have to install it?

marty

@mcostan This should be the case already:

Ubuntu 16.04 example:

apt-cache depends kopano-webapp-plugin-smime

kopano-webapp-plugin-smime
  Depends: kopano-webapp
  Depends: php-kopano-smime
 |Depends: <php5-curl>
  Depends: php-curl
    php7.0-curl
  Depends: php-xml
    php7.0-xml
  Depends: php-bcmath
    php7.0-bcmath
  Conflicts: <kopano-webapp-smime>
  Replaces: <kopano-webapp-smime>
    kopano-webapp-plugin-smime

Did you upgrade your OS and php-version recently? I can imagine some issues there, but that’s something for the admin to double check imo.

mcostan

I updated PHP a few months back and then installed the latest SMIME plugin.

Perhaps it found the old PHP dependency which was installed with the old version of PHP and it thought it was ok…

gabriele

Problem fixed, thanks a lot!

should be the case already:
Ubuntu 16.04 example:

I ran into the same problem after upgrading to Debian 10. php-bcmath is not in the depencies for the package:

@itserv Dependency is added and will soon be on the download server.
