The test case can be distilled down to:

```
ln -sf /usr/share/zoneinfo/EST /etc/localtime
dpkg-reconfigure --frontend noninteractive tzdata
```

On Ubuntu 22.04 (jammy) convert_timezone() in tzdata.config maps EST to America/Indianapolis which is a symlink to America/Indiana/Indianapolis. Bug 1: America/Indianapolis is not an option in debconf and therefore the first geographic area "Adak" is used.

Possible bug 2: convert_timezone() in tzdata.config maps EST to America/Indiana/Indianapolis, but EST is not a symlink to America/Indiana/Indianapolis. If I saw that correctly, EST does not take daylight saving into account.
