failure to build due to deprecated declarations

Patching deprecation results in a large patch with potential regression due to changes in FileChooser API[1].

Until the issue is fixed upstream we can disable deprecation warnings for this package.

The patch makes me slightly uncomfy, given that we should work to fix the warnings instead of disable them, but simply disabling deprecation warnings when both Debian and upstream have been made aware is okay for now.

This bug was fixed in the package network-manager-strongswan - 1.6.0-2ubuntu1

network-manager-strongswan (1.6.0-2ubuntu1) mantic; urgency=medium

  * d/rules: fix ftbfs by disabling GTK deprecation warnings (LP: #2029877).

Upstream replied that they will not rewrite code for gtk4 due to compatibility with gtk3.

[Simon Quigley (tsimonq2)]

The response upstream gave sounds pretty reasonable. Let's continue with this patch, barring any objections or alternative solutions from Debian.

Thanks again for your work on this, Vladimir. :)

Please consider adding a marge request on Salsa, as usual. Thank you

I have submitted the debdiff to the existing Debian bug[1] that was fixed in 1.6.0-2.1.
I will add the MRs where possible in the future.
