cups-pdf ld.so: object 'libsets_pac.so' from /etc/ld.so.preload cannot be preloaded (cannot open shared object file)

[Harald Braun]

I'am using:

-Ubuntu 18.04.2 LTS
-printer-driver-cups-pdf 3.0.1-5
-thunderbird 1:60.5.1+build2-0ubuntu0.18.04.1

No directory /usr/share/doc/cups-pdf

If I want to create a mail as Generic-Cups PDF-Printer under Thunderbird 60.5.1 (64-Bit), the error message "ld.so: object 'libsets_pac.so' from /etc/ld.so.preload can not be preloaded (can not open shared object file)" Appears in the printer selection menu after the entry Generic-Cups-PDF-Printer.

What measures have I tried:
1. Search for file libesets_pac.so. I found it under /usr/lib/x86_64-linux-gnu.
2. Open the file /etc/ld.so.preload as root and prefix the path with 1.. File saved and service CUPS restarted.

Episode:
1. When first printing a Thunderbird mail after the service restarta in the printer selection menu behind Generic Cups PDF Printer NO error message.
2. Each time you print a Thunderbird email, the
Error message again.

Does this issue still affect cups-pdf 3.0.1 packages?

Unfortunately, I can no longer check that. I upgraded to Ubuntu 20.04.1 and the problem no longer exists.

Thanks. Let's close the report then.
