Openh264 asking flatpak >=1.4.2


Hello to all!

I installed EOS 3.6.3 (190909-103118) yesterday and can’t install Steam, spotify and vlc… All of them keep asking for flatpak version 1.4.2 or superior for openh264 dependency.
Checking with “flatpak --version” on terminal says the actual version is 1.3.3.

Here is the eos-diagnostics

Hope it helps!eos-diagnostic-190919_223511_UTC-0300.txt (908,4 KB)

I Hope It helps


Thanks – this is a known issue which we expect to be resolved with the release of Endless OS 3.7.0, currently due in late October. Update: we plan to make a 3.6.4 release in the next few days. In the meantime you can work around this issue by installing these apps from the command line:

  • flatpak install flathub com.valvesoftware.Steam
  • flatpak install flathub com.spotify.Client
  • flatpak install flathub org.videolan.VLC

You will see a warning, but the installation of the app itself will succeed.

Flatpak 1.0.0 or newer required

Thank you very much!


We’re considering making an extra release sooner to fix this issue. Watch this space!
