I came across this SRU pending verification and decided to give it a
try:

1. Launched the VM with `lxc launch ubuntu:24.04 sru-lintian-fix --vm`;
2. Updated apt cache and installed lintian and the Ubuntu Desktop metapackage;
3. Changed upgrader Prompt to normal (still setting up the context).
4. Tried to upgrade with `lxc exec sru-lintian-fix -- do-release-upgrade -d`. 
System upgrade to Resolute was attempted but failed with the error message 
below:

```
Reading state information... Done

Calculating the changes

Could not calculate the upgrade

An unresolvable problem occurred while calculating the upgrade.

If none of this applies, then please report this bug using the 
command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal. If 
you want to investigate this yourself the log files in 
'/var/log/dist-upgrade' will contain details about the upgrade. 
Specifically, look at 'main.log' and 'apt.log'. 


Restoring original system state
```

5. Then I tried with the `--proposed` flag instead of `--devel-release`.
Success in upgrading to Resolute!

I believe we can mark this bug as verification-done. Any objections?
