Bug#995793: exim4-base: /tmp partition has noexec mount option; exim4-base fails

Tue Oct 5 20:49:58 BST 2021

WORKAROUND
Remove the “no exec” from /tmp mount point options in /etcfstab, reboot, then attempt ‘apt upgrade exim4-base’ so that Perl script for ‘exam-config’ can continue. 

OUTPUT of failed upgrade:

~# apt upgrade exim4-base
