Comment 4 for bug 1889057

On Ubuntu 16.04 LTS and 18.04 LTS this installation was done by SessionInstaller ( https://packages.ubuntu.com/bionic/sessioninstaller ). In 20.04 LTS and newer systems this package is removed.

So theoretically speaking the following installation command should make the packagekit available:

```
sudo apt-get install 'packagekit*'
```

and then `shares-admin` will open GNOME Software to install the needed dependencies.
But this does not work. GNOME Software is very useful application!

So the bug is fixable by

a. manual installation of additional packages before launching `shares-admin`:

```
sudo apt-get install nfs-kernel-server samba
shares-admin
```

b. manual download and installation of `sessioninstaller` package from 18.04 LTS and then launching `shares-admin`

```
cd ~/Downloads
wget http://archive.ubuntu.com/ubuntu/pool/universe/s/sessioninstaller/sessioninstaller_0.20+bzr150-0ubuntu4.1_all.deb
sudo apt-get install ./sessioninstaller_0.20+bzr150-0ubuntu4.1_all.deb
shares-admin
```

Any comments?
