[Koha] Koha 18.05 --> 18.11 - Packages held back?

[Craig Butosi]

Hi all,

Running Koha 18.05.05.000 on Ubuntu 16.04.5 LTS. (with MariaDB 10)
currently. Also running memcached and plack.

Packages seem to be holding back for koha-common 18.11.

My sources list is  <deb http://debian.koha-community.org/koha stable main>

Can't seem to figure out what would be holding 18.11 back. Would someone
kindly advise? Is this a missing dependency problem?

Many thanks,
