Owncloud non-functional with "illegal instruction" errors, post-upgrade

[mach-o]

Owncloud has been non-functional since I upgraded it last night. I have also been receiving emails that look like the following every twenty minutes since then:

Subject: Cron root@raspberrypi [ -x /usr/lib/php5/sessionclean ] && /usr/lib/php5/sessionclean
Body: Illegal instruction

This started when I ran a regular upgrade:

$ sudo aptitude upgrade

I am running owncloud on a Rasbperry Pi running the raspbian operating system:

Also: Is it possible this is an unrelated problem in php5? (see especially the output of "php5 -v" above)

[crrodriguez]

"SIGILL" (Illegal instruction) is raised when the CPU does not understand an instruction...

Where did you got PHP5 and does it work by itself.. you can try php5 -i

[crrodriguez]

So, you got the wrong php5 package for your distribution 's ABI, most likely you ended with a armv7 package instead of an armv6. hence illegal instruction.
This is not an owncloud bug, thanks for your report.
