Metadata
Current evaluation
charmcraft pack fails when building with ubuntu@25.10 base and ubuntu@devel build-base due to missing EOL data, remaining unassigned and inactive for over six months.
Suggested action: needs triage
Reason: The issue lacks labels, comments, and maintainer interaction, indicating it has not yet been assessed. Despite its age, it requires triage to determine if the reported build error is still reproducible or if it reflects an intended limitation of using development bases.

### Bug description
Hello,
When trying to build a charm with base = `ubuntu@25.10` and build-base = `ubuntu@devel`, I get the following error when running `charmcraft pack`:
```
The development build-base should only be used for testing purposes, as its contents are bound to change with the opening of new Ubuntu releases, suddenly and without warning.
Launching managed ubuntu devel instance...
Creating new instance from remote
Creating new base instance from remote
Couldn't get EOL data for devel.
```
This is when using charmcraft 4.0.1.
