The second bug-fix release for Audacious 4.0 was released a day ago. Here’s how to install it in all current Ubuntu releases.

While the first bug-fix release brings KDE Plasma 5.18 compatibility, Audacious audio player 4.0.2 includes mainly bug fixes and tweaks for the Qt interface:

• Fixed a regression where the Enter key did not work in the playlist.
• Fixed the seek bar changing width as the time counter increments.
• Fixed the title bar getting stuck showing “Buffering”.
• Added a workaround to ensure that the toolbar is not hidden on startup.
• Fixed the Composer field not being saved when updating ID3v2 tags.
