SUMMARY KDE can no longer be installed or updated via discover/flatpak due to dependency on libopenh264 which is exclusively pulled from hostile third-party server with no way to pre-download by any other way or ignore it. STEPS TO REPRODUCE 1. Try to install/update anything that depends on KDE while being in Russia. 2. Get 403 error from Cisco server (ciscobinary.openh264.org) when sudden dependency on libopenh264 fails. 3. Don't even have a way to feed flatpak "libopenh264-*.so.bz2" manually downloaded via some last remaining usable VPN. OBSERVED RESULT Get locked by third-party server from a corpo. EXPECTED RESULT Use your own servers, support proxies and local mirrors & caches. SOFTWARE/OS VERSIONS Operating System: Gentoo Linux 2.18 KDE Plasma Version: 6.5.3 KDE Frameworks Version: 6.20.0 Qt Version: 6.10.1 Kernel Version: 6.18.1-zen1-fox (64-bit) Graphics Platform: Wayland ADDITIONAL INFORMATION Flatpak known about it for months and views this as intended, tacitly support this and gags protest: https://github.com/flatpak/flatpak/issues/6232 Also, KDE's own bugs.kde.org/enter_bug.cgi page hangs (not the viewing of the rest though) and doesn't allow to write here without VPN either. Not sure if this is result of Russia-side censorship (due to insanely aggressive DPI-filtering, de facto "Iron Curtain 2.0") or server-side. Also see https://bugs.kde.org/show_bug.cgi?id=509636 This also may be happening in Ukraine: https://bugs.kde.org/show_bug.cgi?id=508509
New runtimes moved away from using openh264 so this should no longer be an issue. If you are still seeing this when installing an app then it means that this app using an older runtime version and should be updated. Please report this issue to the app directly on flathub.
