"Reinstallation of pulseaudio is not possible, it cannot be downloaded."

Solution/hack is in next post....

Yesterday I installed packge "pulseeffects" using these commands (for Mint 19.3/Ubun 18.04):
https://github.com/wwmm/pulseeffects/wi ... an--ubuntu

Code: Select all

sudo add-apt-repository ppa:mikhailnov/pulseeffects -y
sudo apt update
sudo apt install pulseeffects pulseaudio --install-recommends

and pulseeffects didn't work (segmentation fault) so I uninstalled it and removed the PPA mentioned above (using software-sources; it doesn't show up in inxi -r); I also uninstalled some packages which were required for pulseeffects and were installed along with pulseeffects (** below).

It seems to have installed pulseaudio 12.2, and I can't get the system to refer to version 11.1

Then ran

Code: Select all

sudo apt update
sudo apt upgrade

without problems.

Now, when I

Code: Select all

sudo apt install pulseaudio-equalizer
...
Some packages could not be installed. This may mean that you have ..etc..
The following packages have unmet dependencies:
 pulseaudio-equalizer : Depends: libpulse0 (= 1:11.1-1ubuntu7.7) but 1:12.2-9~bionic1 is to be installed
                        Depends: pulseaudio (= 1:11.1-1ubuntu7.7)

and

Code: Select all

sudo apt install pulseaudio pulseaudio --reinstall
...
Reinstallation of pulseaudio is not possible, it cannot be downloaded.

and

Code: Select all

 apt policy pulseaudio
pulseaudio:
  Installed: 1:12.2-9~bionic1
  Candidate: 1:12.2-9~bionic1
  Version table:
 *** 1:12.2-9~bionic1 100
        100 /var/lib/dpkg/status
     1:11.1-1ubuntu7.7 500

     1:11.1-1ubuntu7 500
        500 http://us.archive.ubuntu.com/ubuntu bionic/main amd64 Packages

How can I fix it? Remove the pulseaudio section of file /var/lib/dpkg/status?

TIA!

calf-plugins

Solution: I edited the file /var/lib/dpkg/status and removed the package sections which mentioned "1:12" and "pulse" , then ran apt update and apt install pulseaudio --reinstall worked, and now

Code: Select all

$ pulseaudio --version
pulseaudio 11.1
