I think this is simply because Shinken has not been ported to Python 3 for the moment, and it has been the default on Focal.

Is there a pip2 command ?

We ran into the same issue and found a workaround (I would not call it a solution)

TL;DR: install pycurl-7.43.0.3 (exactly that version)

We had Shinken installed on Ubuntu 18 LTS using the pip install method. It was running but not put into production yet. Last week the Ops team upgraded that server to Ubuntu 20.04. That broke the Shinken installation, it would fail to start with an error CURL_OPENSSL_3 not found.

Pycurl was also installed from pip as documented in the installation instructions. At installation time, pycurl seems to have been linked to the libcurl3 library. libcurl3 seems to have been replaced by libcurl4 in 20.04, and there is no libcurl3 package anymore. Which explains the error quite nicely.

We then tried to pip install pycurl --upgrade and noticed it would upgrade pycurl in /usr/local/python3.8/dist-packages - the python3 environment. This does not help Shinken which is using python2.7. The pip command in 20.04 uses python3.

So try to run pip2 instead, but this has been removed from 20.04 as well. We tried a get-pip2.py script referenced in the Webs, which got us a locally installed pip2, but that gave other errors and we did not follow this further.

We then tried to install the latest pycurl (7.43.0.6) manually by downloading the source and executing python2 ./setup.py install. Worked without errors, start Shinken, get a different error. Progress!

That error was about PyUnicode_DecodeLocale. Some web search revealed this is python3 only, and the last version of pycurl that supports python2 is 7.43.0.3.

Repeat the manual installation step with pycurl-7.43.0.3. There, it works! :)

The main issue here is that Shinken seems to require Python 2.x and does not work with Python 3.x (?). Ubuntu 20.04 has deprecated Python2 already, other distributions might follow.

Any plans/status on a Python3 version of Shinken?

Bonsoir
j'étais aussi avec un besoin de shinken mais lors de l'installation j'ai été confronté au même problèmes cités au-dessus.
Du coup il n'existe pas d'alternative si je comprends bien?

upgraded ubuntu 18.04->20.04 with shinken.

My notes:
apt-add-repository universe
apt install python2-minimal
curl https://bootstrap.pypa.io/pip/2.7/get-pip.py --output get-pip.py
python2 get-pip.py

(don't forget adding /usr/local/bin to your path)

(yes it's bionic repos but i don't care)
deb http://fr.archive.ubuntu.com/ubuntu/ bionic main restricted
deb http://fr.archive.ubuntu.com/ubuntu/ bionic universe
deb http://fr.archive.ubuntu.com/ubuntu/ bionic multiverse
apt update
apt install libssl1.0.0

apt install libcurl3 -y

starting shinken.... it's works <3 :)
