New to Fedora...help mounting drives with TrueCrypt

[pbateman]

Hey guys,
I just moved over form Ubuntu to Fedora and I'm going trough the usual growing pains. I installed True Crypt successfully but somehow I cannot mount any encrypted drives or files.
When I attempt to mount a drive or file I get an error that says :

"Failed to obtain administrator privileges: sudo: sorry, you must have a tty to run sudo. To enable use of 'sudo' by applications without a terminal window, please disable 'requiretty' option in '/etc/sudoers'. Newer versions of sudo automatically determine wether a terminal is required ('REQUIRETTY' option is obsolete)

Now I did a bit of research and from what I understand the 'solution' to this is to edit sudoers file and edit it to 'requiretty' is disabled.
Now the issue is i cannot find a place where it shows me how to do this. I am not well versed in CLI so a step by step link would be great so I dont mess up things...

Or is there an easier way to be able to mount drives in TrueCrypt. I read about getting EasyCrypt instead, but wonder if the same issue would suffice.

Thanks!

Truecrypt requires root access if I remember right...
In Fedora, Truecrypt is renamed as Realcrypt and is available from the RPMfusion repositories - see: http://rpmfusion.org/Configuration

If you already have RPMFusion, did you install using:

su -c "yum install realcrypt"

If not, then try that first - the program should prompt you for the root password when you start it up.

Good luck

Oh, and if you want to add sudo back into Fedora, see:

Thanks! I installed Realcrypt this time and seems to be working good now, i can mount my drives.
Thanks for the sudo links as well, most helpful!!

Could someone help me on how can I uninstall truecrypt now that realcrypt is up and running?

Again just judging form my limited experience in Ubuntu I used to be able to go into add/remove software and be able to find a list of all installed software. I cannot seem to do that in Fedora, and when i do a search for truecrypt in add/remove nothing comes up.
I tried using the 'rpm -ev truecrypt' command but did not find that package (not sure if maybe package name is wrong or I am just way off trying to uninstall it that way...) the Truecrypt file was a Tar.gz file and when I extracted it it was an excecutable setup file that I just clicked on to install so not sure if that translates into an RPM file....
Thanks again!!

I had this same problem when I installed Truecrypt on Fedora 15.

Anytime I tried to mount a volume, I got the following error:

"Failed to obtain administrator privileges: sudo: sorry, you must have a tty to run sudo. To enable use of 'sudo' by applications without a terminal window, please disable 'requiretty' option in '/etc/sudoers'. Newer versions of sudo automatically determine whether a terminal is required ('REQUIRETTY' option is obsolete)'

You can bypass the issue using the command line:

$su --login
$Password: enter password
$truecrypt

that activates truecrypt as root and lets you mount and unmount volumes normally through the GUI.

Once you're done, you log out of root via the command line.

$exit

and you're done.

It's not the most elegant solution, but it does allow Truecrypt to work.

i know this is old, but it still shows up on google results for newer releases of fedora.

To mount a TrueCrypt volume, you will need two things:
1- add truecrypt to your sudo list
you can either add your user to the wheel group:
usermod -a -G wheel username

or you can allow yourself to run truecrypt, run "visudo" and add the following at the end of your sudo configuration
username ALL=(ALL) /usr/bin/truecrypt

2- disable the default Fedora option that requires a terminal to use sudo
edit your sudo configuration file by running "visudo" as root
find a line that reads something similar to "#Defaults !requiretty" and uncomment it (remove the #), so it looks like "Defaults !requiretty"

remember to replace "username" mentioned above with your username.

hope this helps. I found out Fedora 25 doesnt have the !requiretty line anymore, so i had to add it.
