I have been trying to install WhatPulse 2.8.4-1633 Ubuntu 64bit on Lubuntu 19.04 x64 without success. The error message is “Application crashed with signal 11!”
In the latest thread I have found with a similar issue the user installed v2.8.3 of WhatPulse on Fedora 30 with a downgrade to openssl 1.0.2 to get around this problem. I would try an older WhatPulse version but I have been unable to locate older versions.
I have versions 4 and 5 of some of the Qt dependencies installed. The WhatPulse install on Linux Mint 19.1 I did recently worked after uninstalling the version 4 ones however the same method did not work for Lubuntu.
