Re: [BackupPC-users] Fedora 41 BackupPC v4.4.0 Perl 5.4.0 undefined import method message

[<02_...@ic...>]

 
Hi Ged,
Just to let you know I removed the "qw(...)" for BackupPC_nightly line 89 and BackupPC_rrdUpdate line 42:
 
Replace:   use BackupPC::Lib qw( :BPC_DT_ALL );
By:             use BackupPC::Lib;
 
and all is fine now.
Many thanks for your help.
 
Alan
