Bug/ crowdsec-nginx-bouncer: is looking for lua 5.1 files instead 5.3

[franciscopaniskaseker]

Describe the bug crowdsec.lua is looking for 5.1 files instead of 5.3

To Reproduce

1. install fresh updated ubuntu
2. setup crowdsec repository
3. install crowdsec and its dependencies according official doc https://doc.crowdsec.net/docs/bouncers/nginx/
4. remove crowdsed (it will note automatically remove /etc/nginx/conf.d/crowdsec_nginx.conf as is expected)
5. do the same procedure to setup (/etc/nginx/conf.d/crowdsec_nginx.conf will not be installed) and nginx -t will start to show errors because crowdsec.lua can not find some lua files

Expected behavior install and reinstall without problem.

Technical Information (please complete the following information):

• OS: ububuntu 20.04 lts updated
• crowdsec-nginx-bouncer is already the newest version (0.0.7).

Additional context Add any other context about the problem here, for example /var/log/crowdsec.log or error messages.

Hello @franciscopaniskaseker ,

The package that you deployed is not from crowdsec stable repository (it is actually in testing). How did you install the bouncer please ?

[franciscopaniskaseker]

I followed these instructions: https://docs.crowdsec.net/docs/bouncers/nginx/

with official repositories: https://docs.crowdsec.net/docs/getting_started/install_crowdsec#install-our-repositories

it was working normally and was communicating with https://app.crowdsec.net/overview . After I removed the nginx bouncer (i needed to disable it a little from nginx and I did not find an official way to do that), i tried to install using same procedures.

Hello @franciscopaniskaseker ,

I don't know how did you get those files since they were only in the testing repository. Can you please try to apt update and upgrade the bouncer from the stable repository please? We have released the v1.0.0 of the nginx bouncer this morning.

[franciscopaniskaseker]

@AlteredCoder thank you. worked. i did

apt clean
apt update
# and the official procedure to setup nginx bouncer.

Cool :)
