Thank you for taking the time to report this bug and helping to make Ubuntu better. What happens when you retry?

```
sudo apt install -f
```

[Nagabhiru Sudhakar (nagabhiru888)]

I am also facing same issue with tzdata 2024a-3ubuntu1.1 and it is a bug with package.

Please check and fix the bug.

[Nagabhiru Sudhakar (nagabhiru888)]

It is critically one and need fix asap.

[Benjamin Drung (bdrung)]

There is no error message in the logs that would explain the failure. Are you willing to help debugging the failure to find (and then resolve) the root cause?

Can you edit /var/lib/dpkg/info/tzdata.postinst and add `set -x` in line two and then run

```
sudo apt install -f
```

[Nagabhiru Sudhakar (nagabhiru888)]

Please refer below error output as per request.

[Benjamin Drung (bdrung)]

So the debconf call fails. Can you run debconf with debug mode?

```
sudo DEBCONF_DEBUG=developer debconf /var/lib/dpkg/info/tzdata.postinst configure 2024a-0ubuntu0.22.04.1
```

The latest version "2024a-0ubuntu0.22.04.1" getting installed rightly if my instance time zone is in UTC.
Othereise it is failing and it shouldn't impact the timezone which set as per our requirment.
Looks it required some fix.
