VirtualMin and Ubuntu server 12.04 - on attempting to activate Google Too-Factor authentication produces the error message: Failed to save two-factor authentication : The Perl module Authen::OATH needed for two-factor authentication is not installed. Use the Perl Modules page in Webmin to install it.
Using the link to "Perl Modules" appears to work OK except for "Simple Moose (Missing 1 modules)".
"Fetching missing prerequisites" results in Pre-requisites Package::DeprecationManager Scalar::Util Test::Requires CPAN::Meta::Check Package::Stash::XS Sub::Exporter Test::Fatal Module::Runtime Params::Util List::MoreUtils MRO::Compat Task::Weaken Class::Load::XS Try::Tiny parent Eval::Closure Devel::StackTrace Package::Stash Class::Load Dist::CheckConflicts Sub::Name Data::OptList Carp Test::More Devel::GlobalDestruction CPAN::Meta::Requirements Digest::HMAC Digest::SHA1 Math::BigInt Test::Simple Moose (Missing 21 modules)
"Continue With Install" ends up with pages of error messages and "Possible endless loop in output detected!"
Any suggestions appreciated before I give two-factor auth. in VMin. up as a bad job!
