[Koha] Koha 20.05 - Upload Cover Image - Software Error (Bug 22027)

[Craig Butosi]

Hi all,

I recently upgraded my Koha version to latest stable (20.05), moved my
OPAC over to https (staff intranet is still http but firewalled), and
upgraded to Ubuntu 18.04 (bionic).

I tried uploading a jpg cover image on one of my pre-existing bib
records, and immediately after I click Process Image, a Software Error
is thrown (exactly like Bug 22027). Here's what I'm getting:

Browser Error:

"Software error:
 not found: No such file or directory at
/usr/lib/x86_64-linux-gnu/perl5/5.26/GD/Image.pm line 64.
For help, please send mail to the webmaster ([no address given]),
giving this error message and the time and date of the error."

Intranet Error Log:

There was mention of Koha system warnings in 22027; I have none. There
was also mention of temp path. In my koha-conf.xml, I have
"<tmp_path>/tmp</tmp_path>"

What could be the problem?

Many thanks!
