I connect via ssh to an OVH hosting, I manage to connect but the problem is that I cannot execute any ubuntu command when I try to install ruby and rails on my server. I am new to ssh ...
formasm@cloudweb-ssh:~ $ sudo su
-bash: sudo: command not found
formasm@cloudweb-ssh:~ $ apt-get update
Reading package lists... Done
E: List directory /var/lib/apt/lists/partial is missing. - Acquire (13: Permission denied)

-bash: sudo: command not found
Thank you for your help.
On OVH Hosting Cloud Web offers, you don't have access to the sudo command nor to the root user: as this is a managed offer, you don't have the administrator rights.
However, it's totally possible to install Ruby on Rails, as Cloud Web provide dependency manager for different languages (gem and bundle for Ruby; npm and yarn for NodeJS etc.).
To install Ruby on Rails on OVH's Cloud Web:
jeanmim@cloudweb-ssh:~ $ export PATH=$PATH:/usr/local/ruby2.6/bin:~/.gem/ruby/2.6.0/bin
jeanmim@cloudweb-ssh:~ $ export GEM_HOME=~/.gem/ruby/2.6.0
jeanmim@cloudweb-ssh:~ $ gem install rails --user --no-doc

You can find a documentation here about how to install a Ruby app on a Cloud Web hosting: https://docs.ovh.com/fr/cloud-web/installer-camaleon-cloud-web/ (in french only from what I can see)
