Apparently, the problem is not related to SoX. It appears to me that “sox já é a versão mais nova” actually corresponds to “sox is already the newest version”, so it seems to be installed already.
I’m moving the report to the bcmwl-kernel-source package because there can be seen a failing post-installation script of bcmwl-kernel-source in the screenshot and in the copied output. ** Package changed: sox (Ubuntu) => bcmwl (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/985845 Title: About use "sox" in "Linux Educational", brazilian distribution for elementary school teather To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/985845/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
