dependency not satisfiable libssl

[nashtrik]

While installing a .deb package with Gdebi, i get the following message..[dependency is not satisfiable libssl1.0.0(>=1.0.0)]. How can this be resolved?I am running latest 5.0 version and libssl version is 1.1.1.Kindly consider the fact  that I am a non-techie and not so command line savvy...though I am not entirely new to linux. I am running this from a 64GB USB 2 Flash drive..full installation. Thanks

As far as I know, this kind of message is generated by GDebi if you want to install an old App that lacks the proper version of a library, due to deprecation.
In your case, the App requires an older library and GDebi never overwrites older libs over the new ones and that is why you got this message.
Ask Jerry for help on installing two different versions of the same lib(s): Is it possible without breaking the system?, or try to find a replacement for the App, that has an Ubuntu 20.04 version on the download page.
Another approach is to use an AppImage version, if available. This might work.

Thanks for the reply. I found a new version of the software which required libssl 1.0.2. I googled it out,found it in packages.debian.org..downloaded and installed from the ftp: site with same Gdebi. running smoothly.
