Ok, let's go. Performing just upgrade after proposed configuration gave me just lubuntu-core update: https://pastebin.com/We1Af6eM
If i perform dist-upgrade it would bring the unity stuff I had said before, I simulate it here: https://pastebin.com/LuJtgHXD Unfortunately when I run install just for lubuntu-default-settings it brings this lots of stuff: https://pastebin.com/mfVsU3fU The indicator also bring a plenty of packages: https://pastebin.com/4bpWJCCc I do not know if lubuntu-desktop is also required to this fix, as part of lubuntu-meta, but it bring few dependencies, nothing to worry about. As I am running on VM I did not care about it and I performed a full dist-upgrade, but I would care about it if I had to do it on my machine. After reboot the machine the sound worked on Firefox but the indicator did not launched pavucontrol as I expected, it is due to no dependency relation between any package tha could lead to pacucontrol package installation. I still had to install it apart, after done that, the tray icon could launch the control as expected. I see there is two things to be done: * A dependency to be add to some package that could lead to the pacucontrol installation; * A deep dependency review in order to clean up unity installation, as well as reduce as few as possible the dependencies -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1710993 Title: PulseAudio requirement breaks Firefox on ALSA-only systems after 55.0.1 update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/indicator-sound-gtk2/+bug/1710993/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
