I can confirm that removing the ESET antivirus software eliminates the error with man.
Also, I saw this text in the ESET user guide at https://download.eset.com/com/eset/apps/home/eav/linux/latest/eset_eav_lin_4_userguide_enu.pdf: NOTE: SELINUX AND APPARMOR ARE NOT SUPPORTED. THEY HAVE TO BE DISABLED PRIOR TO INSTALLING ESET NOD32 ANTIVIRUS. Let me know if you want to continue debugging this or close the issue since it seems to be caused by the ESET software. Thanks for your help and assistance with this issue.
