fixes #7198 We recently bumped the bundled version of PyQt (5.14.2->5.15.4). It seems the new version has a lot more dynamic dependencies. From https://doc.qt.io/qt-5/linux-requirements.html : > From Qt 5.15 onwards, Qt does require libxcb 1.11. Also, the -qt-xcb > configure option got removed that was bundling some of the libs below. We are using the prebuilt wheels for PyQt5 from PyPI. Presumably those had previously been built using the -qt-xcb option.
AppImage binary for Electrum
✓ This binary should be reproducible, meaning you should be able to generate binaries that match the official releases.
This assumes an Ubuntu host, but it should not be too hard to adapt to another similar system. The host architecture should be x86_64 (amd64). The docker commands should be executed in the project's root folder.
We currently only build a single AppImage, for x86_64 architecture. Help to adapt these scripts to build for (some flavor of) ARM would be welcome, see issue #5159.

FAQ
How can I see what is included in the AppImage?
Execute the binary as follows: ./electrum*.AppImage --appimage-extract
How to investigate diff between binaries if reproducibility fails?
cd dist/
./electrum-*-x86_64.AppImage1 --appimage-extract
mv squashfs-root/ squashfs-root1/
./electrum-*-x86_64.AppImage2 --appimage-extract
mv squashfs-root/ squashfs-root2/
$(cd squashfs-root1; find -type f -exec sha256sum '{}' \; > ./../sha256sum1)
$(cd squashfs-root2; find -type f -exec sha256sum '{}' \; > ./../sha256sum2)
diff sha256sum1 sha256sum2 > d
cat d
For file metadata, e.g. timestamps:
rsync -n -a -i --delete squashfs-root1/ squashfs-root2/
