[Touch-packages] [Bug 574287] Re: tasksel: forcefully removes packages when tasks overlap

[Oliver Gerlich]

WTF. I was uninstalling the ubuntu-mate-desktop task with tasksel (while
ubuntu-desktop was still checked in the list), and it removed basically
everything. Afterwards all tasks in the tasksel list were unchecked.
This is definitely not the expected behavior: when I uncheck a specific
task, I don't expect other tasks to be removed as well.

I suggest to disable the package-removal functionality in tasksel.
Alternatively, show a big warning when tasksel is about to remove
anything. There are lots of warning posts about this behavior of tasksel
all over the net, but if the warning does not appear in the application
itself, I'm unlikely to see it before it's too late.

Title:
  tasksel: forcefully removes packages when tasks overlap

Status in apt package in Ubuntu:
  Invalid
Status in tasksel package in Ubuntu:
  Confirmed
Status in tasksel package in Debian:
  Fix Released

Bug description:
  TEST CASE

  1. Boot Lucid LiveCD

  2. run "sudo tasksel" and select "virtual machine host"

  3. run "sudo tasksel" and deselect "virtual machine host"

  4. watch how tasksel uninstalls your system

  OBSERVATIONS

  What seems to happen is that apt vengefully removes ALL of the items
  associated with one task, including several base dependencies of other
  tasks (e.g. ubuntu-desktop)

  One illustrative example is the openssh-server task:
  This one includes the packages openssh-server, tcpd and libwrap0.
  From a normal ubuntu-desktop (e.g. ~liveCD) both tcpd and libwrap0 are 
already installed, and the task-install pulls in only openssh-server.
  However when the task is removed, all these three packages (openssh-server, 
tcpd and libwrap0) are forcefully removed.
  Since libwrap0 is a core dependency of gnome, a large part of gnome will be 
removed alongside the removal of the task.

[Touch-packages] [Bug 1525714] [NEW] [2545A25, Conexant CX20582 (Pebble), Speaker, Internal] No sound at all through speakers on Lenovo Edge 11

[Oliver Gerlich]

Public bug reported:

Sound through speakers of my Lenovo Edge 11 laptop doesn't work in
Ubuntu 14.04 nor 12.04 nor 15.10 (LiveCD); I think it last worked in
10.04 or maybe even only in 8.04.

This was tested on a clean installation of 14.04 (64bit) onto a USB
stick, with all upgrades; but it neither works in my normal installation
(14.04 32bit) which was upgraded over the years. I also tried it on a
LiveCD boot of 15.10 (64bit), and speakers don't work there either.

The hardware appears to be fine though, because after booting, I
sometimes hear the short "drum roll" when the login screen comes up, but
no sound afterwards.

Headphones work fine; microphone appears to work fine as well (at least
the input level in Gnome mixer shows that it gets input).

I had already started to debug the speaker problem some months ago and
it looked like a problem with power saving mode for the sound chip. If
you have any hints how to debug this for real, I'm open for suggestions.
Also, is there any more info I can provide?
