Need to get 26.4 MB of archives.
After this operation, 39.4 MB of additional disk space will be used.
The Perl transition is over, ok 99.5%, 3 packages are left.
What you can do is to run "apt update than apt upgrade", that should be safe for now.
Then check what is left over, maybe it is Perl, perhaps not.
I have checked clamav,
LANG=C apt -s install clamav clamtk libfeature-compat-class-perl libglib-object-introspection-perl
NOTE: This is only a simulation!
apt needs root privileges for real execution.
Keep also in mind that locking is deactivated,
so don't depend on the relevance to the real current situation!
