Cannot install on Ubuntu 19.04 due to missing dependency

So I tried installling the QRL walltet on Ubuntu 19.04. But the installation bails out with an error message:

sudo dpkg -i qrl-wallet-1.1.1.deb
Selecting previously unselected package qrl-wallet.
(Reading database ... 378152 files and directories currently installed.)
Preparing to unpack qrl-wallet-1.1.1.deb ...

dpkg: dependency problems prevent configuration of qrl-wallet:
 qrl-wallet depends on libgconf2-4; however:
  Package libgconf2-4 is not installed.

dpkg: error processing package qrl-wallet (--install):

On Ubuntu 19.04 there is a package called libgconf-2-4 (which I installed) but not one with name libgconf2-4. Apparently QRL is not the only package with this issue, see here: https://github.com/OpenBazaar/openbazaar-desktop/issues/1608

Any ideas how to fix or work around this?
