Support for Ubuntu 24.04; dependency management errors

**Describe the bug**
When attempting to install on Ubuntu 24 with `dpkg`, one gets an error that `dependency problems prevent configuration of batch-explorer`. When attempting to manually install the dependencies with `sudo apt install` and `sudo apt --fix-missing install`, the dependencies still do not install.

**To Reproduce**
Steps to reproduce the behavior:
1. Download the latest .deb from the releases page.
2. `sudo dpkg -i `
3. Observe error in screenshot 1.
4. `sudo apt install gconf2`
5. Observe error in screenshot 2.

Note that this does not happen on systems where gconf2 was installed when the system was at 22.04 and then upgraded to 24.04, putatively since the dependency was installed while the 22.04 repositories are active. Might one attempt to manually re-add the 22.04 repositories? This does not seem like best practice.

**Expected behavior**

I'd expect the .deb to have dependencies that are available on Ubuntu 24.04, or for there to be a workaround.

**Screenshots**

**Version (please complete the following information):**
- OS: Linux, Ubuntu 24.04.3 LTS
- Version: 2.22.0-stable.1076_amd64

Thank you!
