Issue with gitlab-shell while updating gitlab to 11-11-stable

Hi,

I’m trying to update Gitlab following this guide:
https://docs.gitlab.com/ee/update/upgrading_from_source.html

At step 8, I have the following error:

# sudo -u git -H make build
make: *** No rule to make target 'build'.  Stop.

Previous step was a success so I’m stuck with the error above. How can I fix this ?

sudo -u git -H git fetch --all --tags
sudo -u git -H git checkout v$(</home/git/gitlab/GITLAB_SHELL_VERSION)
sudo -u git -H bin/compile

that worked for me. FYI
