Errors were encountered while processing: initramfs-tools

[MotoTom]

Hi All,

Last week I upgraded from Ubuntu 16.01 to Ubuntu 18.01 and am now running  4.4.132-1075-rockchip-ayufan-ga83beded8524.

While my core functions are working (SFTP and Samba) I keep getting "Errors were encountered while processing: initramfs-tools" when trying to update. I'm not particularly experienced in reading logs so below is the most recent apt-get upgrade log in the hopes some one can point me to a solution for this error. I suspect that failure to fix this will prevent future image upgrades.

Any help is greatly appreciated.

Many thanks.
Tom
