debdiff attached for Noble.

Why does it have an explicit dependency on the library package? Using the -dev instead should be enough and would avoid similar problem next time libtins changes ABI.

[Sudip Mukherjee (sudipmuk)]

Yes, completely agreed. Just wanted to have a smaller diff compared to Debian but I didn't think about the similar problem next time.

Adding modified debdiff.

[Simon Chopin (schopin)]

I had a look at the Debian tracker for this package, and I'm guessing it's entangled in a similar transition, so I'd suggest upstreaming the patch there as well.

I removed the ubuntu-sponsors tag, please add it back when you feel you've addressed my question :)

[Paride Legovini (paride)]

Some questions on:

- libtins4.0 (>=4.0),
- libtins-dev (>=4.0),
+ libtins-dev,
+ libssl-dev,

I don't think the versioned build depends

  libtins-dev (>=4.0),

was problematic. By dropping the (>=4.0) you are just allowing older versions of the package to satisfy the dependency, and we are not interested in that.

2. From a quick test, looks like we actually need that explicit

  libssl-dev

build-depends you added. Do you have an idea on how it was building before, without that? If you don't, don't dig too much.

[Sudip Mukherjee (sudipmuk)]

1. debdiff updated with versioned dependency on libtins-dev.
2. Sorry, no idea how it built before. Last time it was built for Jammy. I am guessing it must be something from new libtins.

[Paride Legovini (paride)]

Thanks! The diff now LGTM. I adjusted the bug subject as what we have here is a "fails to build from source" issue.
