Plesk 12.5 [Debian 7.9] Error by create a SSL

Sn0x · March 19, 2016, 4:34pm

Hey, i have set a new Debian 7.9 vServer with Plesk 12.5.

Now im have the Problem that Plesk/LetsEncrypt me say:

Fehler: Fehler bei der Installation des

What can i do to Fix it ?

I found out that letsencrypt uses a local python instead of the system wide one. So, here’s the fix:

Go to your server’s shell as root
cd /usr/local/psa/var/modules/letsencrypt/venv/bin
./pip install --upgrade cryptography

Got this Error with you Fix

yakuza2611 · March 20, 2016, 8:02pm

get the same error as Sn0x

yakuza2611 · March 20, 2016, 8:27pm

i found out: for debian and ubuntu try this before:

sudo apt-get install build-essential libssl-dev libffi-dev python-dev

Sn0x · March 20, 2016, 8:57pm

Works!! Nice thanks @all for you Support.

ringfotograf · March 21, 2016, 9:46pm

It works ! Thanks to @Lyve and @yakuza2611 !

Lyve · March 21, 2016, 10:21pm

You’re welcome

I already had a development environment set up so I didn’t know about the compiler dependencies, good that yakuza found out

josvh88 · March 27, 2016, 11:04am

Thanks @Lyve and @yakuza2611,

However, I get the same error as Sn0x.

sudo apt-get install build-essential libssl-dev libffi-dev python-dev

didn't work either (apt-get not found), so I tried the same command with yum:

sudo yum install build-essential libssl-dev libffi-dev python-dev

It does something (I'm sorry, I am very new to all this command line thingy), but it fails. I added some translations to the result:

I think the problem is that apt-get uses different sources than yum, is that correct?
Also, does anyone know how to get around this problem to install Let's Encrypt correctly?

serverco · March 27, 2016, 12:38pm

What operating system are you using ?

apt-get is normally used by debian based sysems ( debian, ubuntu etc)
yum is used by CentOS and related systems.

The topic title is about Debian 7.9 - however your system uses yum rather than apt-get I'm guessinng that your operating system isn't Debian 7.9

josvh88 · March 27, 2016, 1:29pm

You are right. Shame on me I didn’t read the title that good, I got here by Googling the error.

I’m running CentOS 7 (64bit).

serverco · March 27, 2016, 1:35pm

I can’t split this topic - so potentially starting a new topic - for the correct OS maybe useful. Although hopefully one of the LE staff ( @jsha ) may well split this off into a new topic

What specific error are you getting (the errors installing certain “apt” packages is because you are using yum, and those aren’t the correct package names in centos) I’m not sure what packages you really need though without knowing what error you are trying to overcome.

josvh88 · March 27, 2016, 2:04pm

I installed Let's Encrypt via Plesk's extension manager. The install was succesful.
When I go to the LE extension and click on a domain to install the SSL certificate, it shows me the same error as in the first post of this topic:

Fout: Het installeren van het Let's Encrypt SSL-certificaat is mislukt: Failed letsencrypt execution: Traceback (most recent call last):

ContextualVersionConflict: (cryptography 1.1 (/usr/local/psa/var/modules/letsencrypt/venv.YVabb/lib/python2.7/site-packages), Requirement.parse('cryptography>=1.3'), set(['PyOpenSSL']))

Edit: I solved the problem running the following commands:

sudo yum install gcc libffi-devel python-devel openssl-devel

pip install cryptography
pip install --upgrade pip

cd /usr/local/psa/var/modules/letsencrypt/venv/bin
./pip install --upgrade cryptography

Right now, adding a certificate in Plesk works.
