How to enable the Edit button in Shutter?

I found a solution here: http://ubuntuhandbook.org/index.php/2018/04/fix-edit-option-disabled-shutter-ubuntu-18-04/. I can confirm that it works for Budgie 18.04.

1. Download and install the libgoocanvas-common and libgoocanvas3 packages.

   Either use Gdebi package installer (available in Ubuntu Software) or run command in terminal (press Ctrl+Alt+T) to install the package:

   sudo dpkg -i ~/Downloads/libgoocanvas3_1.0.0-1_amd64.deb
   sudo dpkg -i ~/Downloads/libgoocanvas-common_1.0.0-1_all.deb
   sudo apt-get -f install
   

2. Finally download & install libgoo-canvas-perl package:

   Also install the package via Gdebi or terminal command, since Ubuntu Software doesn’t solve dependencies automatically:

   sudo dpkg -i ~/Downloads/libgoo-canvas-perl_0.06-2ubuntu3_amd64.deb
   sudo apt-get -f install
   

To apply changes, kill Shutter process or restart your computer!

There is unofficial PPA with newer version of Shutter plus the required dependencies for Ubuntu 18.04 and 18.10. See https://www.linuxuprising.com/2018/10/shutter-removed-from-ubuntu-1810-and.html

sudo add-apt-repository ppa:linuxuprising/shutter
sudo apt-get update
sudo apt install shutter

and restart Shutter.

Thanks to the answer of budgie. That solution worked fine for me as well.

Just to clarify in this thread, this is what I did:

1. Downloaded these three packages in Chrome:
   libgoocanvas-common_1.0.0-1_all.deb
   libgoocanvas3_1.0.0-1_amd64.deb
   libgoo-canvas-perl_0.06-2ubuntu3_amd64.deb

2. Clicked on the downloaded files in Chrome (or File Browser) and installed the package with Ubuntu Software.

3. Restarted the computer and then the Edit button was enabled.
