Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

On first reading, this looks like a configuration issue, possibly a misconfiguration / choice during an upgrade

* nginx is failing to start due to a missing file: feb 24 14:12:22 thinkPad-E58-2 nginx[142256]: 2025/02/24 14:12:22 [emerg] 142256#142256: open() "/etc/nginx/sites-enabled/sonarqube.thinkPad-E58-2.com.com" failed (2: No such file or directory) in /etc/nginx/nginx.conf:61
* by default, `nginx` will load all files in `/etc/nginx/sites-enabled/` (snip below)

 41 access_log /var/log/nginx/access.log;

 58 ##
 59
 60 include /etc/nginx/conf.d/*.conf;
 61 include /etc/nginx/sites-enabled/*;
 62 }

* the file is unavailable -- it could be a dead link?

could you provide the following info:

1. any nginx config that is shareable and relevant
2. the contents of `/etc/nginx/sites-enabled/`
3. if there are any links in `/etc/nginx/sites-enabled/`, could you ensure that the links are not broken?

in a test setup i can reproduce this with a broken link

1. lxc launch ubuntu-daily:oracular
2. sudo apt install nginx
3. touch /tmp/nginx-site.com
4. ln -s /tmp/nginx-site.com /etc/nginx/sites-enabled/nginx-site.com
5. service nginx restart
<all is well>
6. rm /tmp/nginx-site.com
7. service nginx restart
Job for nginx.service failed because the control process exited with error code.
See "systemctl status nginx.service" and "journalctl -xeu nginx.service" for details.
