[install error] Truely wanna new version could support ubuntu20.04

[Tipriest]

Hello, my system is ubuntu20.04, and when i install pakeplus version >= 0.4.5, no matter what kind of install format, I will meet some same problems, most commonly:
when i dirtctly install deb file or use alien to convert rpm file to deb file, i will meet libwebkit2gtk version error, like this:

> sudo dpkg -i PakePlus_0.4.5_amd64.deb

when I directly use .AppImage, it tells me that the GLIBC version is lower, this is more hard to config for a ubuntu user, so I truely expect that the maintainer could do a adaption to ubuntu20.04, because there are still lots of users who are still using this version of system for a long period of time.

tks so much! And this is really a good job.
