Plesk 11 - Memcache - libssl update ?

[nicdouille]

Hello.

I'm running a server running Ubuntu 12.04 LTS 64 Bits with plesk 11.09

I would like to install memcache

I did follow this tutorial : https://www.digitalocean.com/community/articles/how-to-install-and-use-memcache-on-ubuntu-12-04

I'm blocking on installing php-pear
I made a simulation on the installation, and i saw that it will update two packages :

Inst libssl1.0.0 [1.0.1-4ubuntu5.5] (1.0.1-4ubuntu5.8 Ubuntu:12.04/precise-updates [amd64]) [libssl1.0.0:amd64 on libssl1.0.0:i386] [libssl1.0.0:i386 on libssl1.0.0:amd64] [libssl1.0.0:i386 ]
Inst libssl1.0.0:i386 [1.0.1-4ubuntu5.5] (1.0.1-4ubuntu5.8 Ubuntu:12.04/precise-updates [i386])
Conf libssl1.0.0 (1.0.1-4ubuntu5.8 Ubuntu:12.04/precise-updates [amd64])
Conf libssl1.0.0:i386 (1.0.1-4ubuntu5.8 Ubuntu:12.04/precise-updates [i386]

Can i make the installation, and the two updates, without breaking my plesk installation ?

Is there another way, installing memcache, for my server (Ubuntu 12.04 LTS 64 Bits with plesk 11.09) ?

Thanks for reading and helping me
