MongoDB mongorestore failure: locale::facet::_S_create_c_locale name not valid

Question

I created a dump with mongodump on computer A (ubuntu 12.04 server). I moved it to computer B (ubuntu 12.04 server) and typed:

mongorestore -db db_nam

Answer 1

Actually it isn't strictly related to MongoDB. Somehow the language on computer B was not defined correctly. I managed to fix it by typing:

sudo locale-gen en_US en_US.UTF-8
sudo locale-gen it_IT it_IT.UTF-8
sudo locale-gen xx_xx xx_XX.UTF-8 ...
sudo dpkg-reconfigure locales

These commands will generate and configure the needed locales. After those steps mongorestore got back working as usual.
