Thank you for taking the time to report this bug and helping to make Ubuntu better.
The libtxc-dxtn-s2tc0 has been removed from later versions of Ubuntu and it has been removed as a dependency in the Ubuntu steam packaging since 1:1.0.0.67-2ubuntu1 (Ubuntu 21.04). Therefore I am marking this bug as fixed released. ** Changed in: steam (Ubuntu) Status: New => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1679725 Title: s2tc dependency broken on zesty To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/steam/+bug/1679725/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
