Mint 22 Cinnamon

Bug description

I open cinnamon-settings from the terminal and click on the Sound icon. The sound configuration does not open.

Steps to reproduce

Start cinnamon-settings.
Click on the Sound icon.
The sound setting does not open.

Expected behavior

The sound setting should open.

Additional information

This happens after an upgrade from Mint 21.3 Cinnamon to Mint 22 Cinnamon.

I reinstalled pipewire and pipewire-bin.

The terminal shows the following backtrace:

https://packages.ubuntu.com/ did not return any result for libFLAC.so.8.

I also cannot load the sound applet sound@cinnamon and the third-party applet sound150@claudiux (@claudiux)

After uninstalling pipewire, enabling pulseaudio and rebooting (as described in https://www.linuxmint.com/rel_wilma.php), the sound setting cannot be opened either.

The text was updated successfully, but these errors were encountered:

@sphh
Maybe apt install libcvc0? EDIT: I've used apt-file search libcvc.so.0 to know this packet name.

Also, take a look to https://github.com/orgs/linuxmint/discussions/462

claudiux · 2024-09-24T21:29:36Z

@sphh
For libFLAC: apt install libflac++10

sphh · 2024-09-24T21:29:58Z

@claudiux: I believe, libcvc.so.0 is already installed and this confirms it:

$ sudo apt install libcvc0
[…]
libcvc0 is already the newest version (6.2.0+wilma).

If I read the error message correctly, the problem is the missing libFLAC.so.8.

Re your link. It proposes

$ pactl info

And after sudo apt install libflac++10 (which was not installed):

No libFLAC.so.8 :-(

sphh · 2024-09-24T21:34:42Z

sudo apt -f install installs nothing …

claudiux · 2024-09-24T21:38:48Z

Mmmh. apt install --reinstall pulseaudio-utils to force installation of latest version of pactl?

sphh · 2024-09-24T21:41:29Z

No luck either.

I also checked the version of libcvc0. It's 6.2.0+wilma.

claudiux · 2024-09-24T21:43:12Z

Have you used mintupgrade to upgrade to LM22?

sphh · 2024-09-24T21:44:47Z

Yes, I did.

sphh · 2024-09-24T21:51:39Z

$  ldd /usr/lib/x86_64-linux-gnu/libcvc.so.0 | grep libFLAC
	libFLAC.so.8 => not found

So I believe that my libcvc.so.0 has been linked with libFLAC.so.8 and not libFLAC++.so.10. The question is: Why?

claudiux · 2024-09-24T21:54:49Z

pactl --version? Mine is 16.1.

sphh · 2024-09-24T21:58:25Z

$ pactl --version
pactl: error while loading shared libraries: libFLAC.so.8: cannot open shared object file: No such file or directory

claudiux · 2024-09-24T22:03:11Z

Voilà! Why is your libcvc.so.0 linked against libFLAC.so.12 and mine against libFLAC.so.8? 🤔

sphh · 2024-09-24T22:10:44Z

My package is from this repository:

claudiux · 2024-09-24T22:18:12Z

Maybe there is a workaround, but I don't like it.

cd /usr/lib/x86_64-linux-gnu
sudo ln -s libFLAC.so.12.1.0 libFLAC.so.8

sphh · 2024-09-24T22:21:38Z

I now reinstalled the libcvc0 package, but no luck.

No, you are right, that's nasty …

Why does my installation fetch an old version of libcvc0???

sphh · 2024-09-24T22:29:19Z

BTW: Linking libFLAC.so.12.1.0 and libFLAC.so.8 removes all the errors described above. But I consider this not as a solution.

claudiux · 2024-09-24T22:29:36Z

Maybe restoring your old system with Timeshift then running again:

apt install --reinstall mintupgrade
sudo mintupgrade

???

claudiux · 2024-09-24T22:31:42Z

BTW: Linking libFLAC.so.12.1.0 and libFLAC.so.8 removes all the errors described above. But I consider this not as a solution.

You're right; this is not a solution.

I also tried two hand-picked main package servers to reinstall libcvc0. The library libcvc.so.0 is still linked to libFLAC.so.8 in both cases!

claudiux · 2024-09-24T23:24:13Z

All outputs seem OK.

I don't know the origin of this problem. Ping @mtwebster

sphh · 2024-10-01T12:58:03Z

I did some more investigations, after I updated my other computer to Wilma (where libcvc.so.0.0 correctly points to libFLAC.so.12).

I downloaded the libcvc0_6.2.0+wilma_amd64.deb on both computers.
Both deb files have the same md5sum: ecd64708e0abca32119288fc4f103f00
On both computers I pulled the file libcvc.so.0.0.0 out of the deb file.
Both libraries have the same md5sum: 8044f8842f556de69d7cfe15f0369e57
I run ldd libcvc.so.0.0.0 | grep libFLAC on both computers.
They show a different output:
- libFLAC.so.8 => /lib/x86_64-linux-gnu/libFLAC.so.8 (0x00007e45730c8000)
- libFLAC.so.12 => /lib/x86_64-linux-gnu/libFLAC.so.12 (0x000079acf86a0000)

🤔 I am afraid that is way above my pay grade!
