Thunderbird - installation Ubuntu error message

In the process of installing (yay!) Ubuntu package onto my PC - i came across an error message -
E-Sub process /usr/bin/dpkg returned an error code (1)

Following packages in a broken state
thunderbird-locale-es, thunderbird-locale-en etc.

All relate to various locales it seems. Please advise to repair/fix this as the install process stops at this point.

Thanks,
Sass
