Thanks for taking the time to report this bug and trying to make Ubuntu better.

Checking the journal of the nginx service you will be able to see:

nginx: configuration file /etc/nginx/nginx.conf test failed

This indicates that your config file is not valid, it might have a syntax issue or some invalid field. Please re-check its content before restarting the service.

Moreover, your dpkg log shows that you have a dependency issue with your firefox-locale-en package.

Since this is likely a local configuration issue, I am marking this bug as Invalid. If you disagree please set it back to New with some reasonable explanation.

I don't want to counter you really, Lucas, but the underlying error is here in journalctl:

nginx: [emerg] dlopen() "/usr/share/nginx/modules/ngx_stream_geoip2_module.so" failed (/usr/share/nginx/modules/ngx_stream_geoip2_module.so: undefined symbol: ngx_stream_core_module) in /etc/nginx/modules-enabled

This is a known issue, and seen in Debian as well, but we'd have to do a no change rebuild in updates to make this rebuild and recompile, it's something that we need to work on and figure out 'best approach'.

[Thomas Ward (teward)]

I just did a default install of NGINX on a 20.04 environment and did an upgrade to 22.04 and can't replicate this.

What architecture are you on? Is this a VM? Is this WSL? Can you share your config (and sanitize things like base hostnames, etc. out of things) so we can have a test example for us to do testing?

I'm going through some old bugs.

I'm also unable to reproduce this. If we could get some more information such as what your /etc/nginx/nginx.conf looks like, that may be helpful in reproduction.

Looking online I see a few different reports which seem similar, where each have differing solutions. For example [0] has a solution of removing old nginx modules. This isn't ideal but could be useful. If this is the case and easily reproducible it should be handled by us in the maintainer scripts. Other similar looking bugs[1] have solutions such as manually linking missing modules.

It's hard to tell exactly what's going on without being able to reproduce it. Therefore, I'm setting the bug to incomplete since it is not easily reproducible and not getting much traction.

Please comment if this bug should be looked into more, and provide information such as your /etc/nginx/nginx.conf.
