Upgrading PLesk 10.3.1 / There are 3 packages required for the product to function pr

[mandi22]

I am trying to upgrade PLesk 10.3.1 to 10.4.4 on CentOS 5.2
I get the following notification on the autoinstaller process:

There are 3 packages required for the product to function properly, which
were not found in your system.
Unfortunately I see no information on what the missing packages are and I do not dare upgrading since I am afraid of some terminal error with Plesk.
Suggestions?

Do you have any useful information from /tmp/autoinstaller3.log ?

Hello Igor,
Nothing special shows up in the logs.
I have attached the full log in the post and the only Error I noticed was the following:
