1. grab/download yourself a copy of truecrypt binaries from here: http://dwaves.de/2016/02/26/is-truecrypt-insecure/
wget http://dwaves.de/software/truecrypt/truecrypt-7.1a-linux-x86.tar.gz; # if you are running 32Bit Linux

wget http://dwaves.de/software/truecrypt/truecrypt-7.1a-linux-x64.tar.gz; # if you are running 64Bit Linux

sha256sum truecrypt-7.1a-linux*; # generate checksum
# should be 32Bit: 9d292baf87df34598738faef7305cddaa15ea9f174c9923185653fb28f8cfef0 and
# should be 64Bit: 43f895cfcdbe230907c47b4cd465e5c967bbe741a9b68512c09f809d1a2da1e9

tar fxvz truecrypt-7.1a-linux*; # unpack

chmod u+x truecrypt-7.1a-linux*; # make executable

./truecrypt-7.1a-linux*; # execute setup... rest should be self-explaining

install-truecrypt-gui-under-linux

if you then fireup

truecrypt

you should get that gui:

truecrypt_gui
