Thank you for taking the time to file a bug report.

From DpkgTerminalLog.txt:

Sep 17 08:06:47 aquadevida-IdeaPad-5-14ITL05 nginx[10522]: nginx: [emerg] getpwnam("test_domain") failed in /etc/nginx/nginx.conf:1
Sep 17 08:06:47 aquadevida-IdeaPad-5-14ITL05 nginx[10522]: nginx: configuration file /etc/nginx/nginx.conf test failed

The getpwnam call tries to find information about the user specified in its argument; in this case, "test_domain". It seems like you may have modified the configuration file by hand, since "test_domain" is not a username that the package would create/use.

Since it seems likely to me that this is a local configuration problem,
rather than a bug in Ubuntu, I am marking this bug as 'Incomplete'.

However, if you believe that this is really a bug in Ubuntu, then we would
be grateful if you would provide a more complete description of the problem
with steps to reproduce, explain why you believe this is a bug in Ubuntu
rather than a problem specific to your system, and then change the bug
status back to "New".

To follow up on Sergio's message, please include your `/etc/nginx/nginx.conf` file here if you believe this is a problem in the package and not your specific configuration. It's more than likely you have a `user test_domain;` option in your configuration, and that is not a valid user, meaning you're using a bad config.
