I need some help getting a Go application working on YunoHost.
I’ve got some of it working but I keep getting Fail2Ban errors when trying to install it.
The app’s github is here: GitHub - ld3z/nonbiri_ynh: Nonbiri, is a self-hosted back-end and front-end for MangaDex packaged for YunoHost
Which is based off: GitHub - rs1703/nonbiri: Nonbiri is a self-hosted back-end and front-end for MangaDex.
Any help on this, I would be very appreciative, thank you!!!
First you need to create a testing branch and work on it. Then create a merge request and comment !testme so we will have some feedback from the CI. It could be usefull to help you !
So, I’ve created the testing branch and merged them, but it seems that the !testme is a YunoHost-Apps exclusive thing. How do I add it to that and get it working?
Yes indeed. You can transfer your repo to our organization so that our bot can access it. I’ll invite you to the org.
Thank you! 
So when installing the application I get the Fail2Ban error that I got on my Virtualbox testing. I have been checking the YunoHost app helper and I think I know how to fix it but I’m not sure.
Here’s the log from the YunoHost app bot:

94289 ERROR Unable to install nonbiri: An error occurred inside the app installation script

You may just comment it. I’m not quite sure about fail2ban config in the scripts. I didn’t read the fail2ban section in the packaging docs 
. OK I’ll do it 
Edit : here are the docs
https://yunohost.org/en/packaging_apps_helpers#fail2ban
Alright, so I tried it and it seems that it isn’t a problem anymore but, now I get nginx errors.

--- FAIL ---
In the install script remove the open port directive. This port doesn’t need to be open to the outside of the server.
In your nginx.conf add
proxy_pass http://127.0.0.1:42071
I advise you to install yunohost on a virtual machine for testing. Launching test on the ci takes time and it’s not convenient for starting to package. Sometimes it’s only a dot you forgot to type. Waiting hours to get this log is 
Ok! So I added the proxy_pass http://127.0.0.1:42071 to the nginx.conf and edited the install script, the nginx errors are gone now (yay!) but, I can’t seem to access it via the url or ip address. Do I possibly have to add a command to run the application file that gets installed?
This branch should be a good starting point (although it doesn’t work yet): GitHub - YunoHost-Apps/nonbiri_ynh at test
According to the logs, a config file seems to be needed, but I can’t find any mention of this upstream
error reading config file: While parsing config: unexpected end of JSON input
Looks like it should be nonbiri.json: nonbiri/prefs.go at c0baeb843134dd731e9b47a6064cce1c935c9479 · rs1703/nonbiri (github.com)
Ok, thank you for fixing it, it seems to install with no problems and the web ui is accessible using the ip and port. I run a VM to test the package, and when I goto the browse section to actually read it, it gives a image that seems to be a placeholder when it can’t get the manga. I had this error when installing it just from the git itself without YunoHost, and it seems it can’t access the MangaDex’s api, but when I check the logs on YunoHost I see no problem. (I’m just glad the web ui works at this point…) thank you @ericg
I hopefully plan to go ask them (MangaDex) on their discord server about it, hopefully they can share some insight as well.
