truecrypt "bad file descriptor" - one of the reason is because cannot resolve host

To make TrueCrypt working again make sure that your hostname is in the /etc/hosts file.

Add the below lines in case they are missing from file having replaced "REPLACEWITHYOURHOSTNAME" with your host name (goes after @ symbol in terminal).

Code:

127.0.0.1    REPLACEWITHYOURHOSTNAME    localhost.localdomain    localhost
::1    REPLACEWITHYOURHOSTNAME    localhost6.localdomain6    localhost6
