I have searched this forum to see if anyone else has had this problem.
Last week I upgraded from Kubuntu 18.04 to Kubuntu 20.04. This was an UPGRADE, not a clean install. Now I cannot sign an adif file to upload to LOTW. When I attempt to do so, I get the following error message:
Starting export to adif ...
Export to the adif file completed.
Signing adif file ...
/usr/bin/tqsl: error while loading shared libraries: libwx_gtk2u_core-3.0.so.0: cannot open shared object file: No such file or directory
Kubuntu 20.04 does not have libwx_gtk2 libraries in the repository, it has libwxgtk3.0-gtk3-0v5. The Kubuntu 20.04 Release Notes say that
"All KDE4 and Qt4 libraries and applications have been removed from the 20.04 archive, and are therefore not supported".
I have verified that the TQSL app (v. 2.5.5) is working. I used it to sign and upload the adif file that cqrlog created.
Thanks for any help you can give me.
