The lack of that package is not a Sigil bug but instead a missing distribution package that should already exist on your platform.

We do not make nor endorse the flatpak builds. A third party handles that.

Your installed Qt6 version (Qt 6.2.4 based on your post) is too old to build Sigil-2.3.0.

Sigil 2.3.0 no longer requires Qt6-compat5 to build, but it does require Qt6 version 6.4.0 or later to build.

If you build things yourself, you can always use the python module "aqtinstall" to grab a local version of Qt 6.7.2 for your platform and build against it yourself.

See this thread in our MobileRead Sigil User forum for more detailed instructions:

Starting with post number 33 with the specific instructions in post number 35.

The best place to get help building Sigil is in our Sigil Forum on www.mobileread.com (See our README.md). Not here in issues. So closing this. Please ask for help in our User Forum.

2.2.0 should build with Qt6.2.4. we didn't bump the minimum to Qt6.4 until Sigil 2.3.0. But regardless... qt6-5compat-dev package is available from Ubuntu 23.10 (Mantic) on. As is Qt6.4. Something is messed up. You're indicating Sigil 2.2.0, but the build log shows it's clearly looking for Qt6.4--which didn't become the Qt minimum until Sigil 2.3.0.

Need much more clarification to help. As Kevin mentioned, take this to our Mobileread user forums as this not really a bug.
