Mounting a Truecrypt volume fails with 'Failed to create a file or directory in a temporary directory.' about cryptonite HOT 11 OPEN

Should have also said - this is the stock ICS ROM from Samsung.

If I create the missing directory - the truecrypt command completes sucessfully - and I can mount the container:

"
df | grep /sdcard/mnt
/mnt/sdcard/mnt 31M 75K 31M 1024
"

I don't know if I did or didn't do something to cause that directory to get created - or whether it's in a different place because of the full disk encryption?

That's a bug in l.54 of https://code.google.com/p/cryptonite/source/browse/tc/tc-android.patch : The application directory is hardcoded to /sdcard/Android/data/csh.cryptonite, which doesn't seem to be the right place on your phone. Possible fixes:

• Find out what the correct location on your phone is, and use that in case /sdcard/Android/data/csh.cryptonite fails. What's the location that's flashing up when you select "Use external storage" in the Cryptonite preferences menu?
• Get the correct external application directory from C. No idea how to do that (see https://developer.android.com/reference/android/content/Context.html#getExternalFilesDir(java.lang.String) for the Java version).
• Find out what the correct location on your phone is, and use that in case /sdcard/Android/data/csh.cryptonite fails. What's the location that's flashing up when you select "Use external storage" in the Cryptonite preferences menu?
• Use the TMPDIR environment variable, as does the original truecrypt code. Supposedly there must have been some problem when I first tested it, otherwise I wouldn't have edited the original truecrypt code. Maybe it was a permissions problem.
  • Write the external application directory to some string with the Cryptonite app and read this string from the truecrypt C code.

The location that flashes up when I select 'Use external storage' is:

/mnt/sdcard/Android/data/csh.cryptonite/cache

Thanks for reporting, the "cache" subdirectory might explain the bug. Will try to fix this in the near future.

It happens me too with KUbuntu 12.04 in a regular PC.
This is the exact error message:

Failed to create a file or directory in a temporary directory.

Please make sure that the temporary directory exists, its security permissions allow you to access it, and there is sufficient disk space:
/tmp/.truecrypt_aux_mnt256

@sanete: do you mean that it happens when you use the Linux version of truecrypt?

Yes, but other computers I have with the same operating system work ok.
Surely it is some misconfiguration.

After rebooting, it works now!

So how can i change default path to your truecrypt TMPDIR to use it on internal sdcard? thanks!

do I understand correctly that, if the TMPDIR variable is set, it should use that instead of flash card ?

if so, it's just a matter of figuring one's way around the pains of setting variables ( http://stackoverflow.com/questions/3736062/how-to-set-and-use-an-environment-variable-in-android-test )

question to Christoph:
why not use /cache as the resting place for TC's temp files?

ps
sorry for doublepost.
emails being public is not very comfy (Ukraine issues, I have them ;) )
