#968 Unable to open ~/.mtpz-data for reading, MTPZ disabled.

[Damn]

The mtp-tools always reports "Unable to open ~/.mtpz-data for reading, MTPZ disabled." at start, and it is reported even before "libmtp version 1.1.6".

For example :

jinoh67@JINOHPC:~$ mtp-detect
Unable to open ~/.mtpz-data for reading, MTPZ disabled.libmtp version: 1.1.6

Listing raw device(s)
Device 0 (VID=04e8 and PID=6860) is a Samsung Galaxy models (MTP).
   Found 1 device(s):
   Samsung: Galaxy models (MTP) (04e8:6860) @ bus 3, dev 10

So I created the directory "~/.mtpz-data" and it now reports :

Unable to read MTPZ public exponent from ~/.mtpz-data, MTPZ disabledlibmtp version: 1.1.6

The weird message could also be found at the '69-libmtp.rules' at the first line, which was not commented.

I compiled libmtp-1.1.6 with

./configure --prefix=/usr
make
sudo make install

Any problems?

[Damn]

At least, the libmtp could make the file ~/.mtpz-data at first time.

This error is found on src/mtpz.c at line 130 in function mtpz_loaddata.

No manuals exist for how to create the configuration file.

Same issue there.
Just installed mtp packages from Ubuntu Saucy via "sudo apt-get install mtp-tools mtpfs"
Any suggestion ?

[Anonymous]

This method works.
Thanks.

Same issue here after installing mtp-tools via apt-get.

[Alex Franchuk]

I believe this is because the person who merged the mtpz work on libmtp back in missed a file. If you copy the file from this project:
https://github.com/kbhomes/libmtp-zune

(in the src directory) then it works. However, I don't see why this file needs to exist, the data could simply be stored in libmtp.

Is there a workaround?

[Anonymous]

If your device is not MTPZ device, it does not automatically create mtpz-data. You can go to find mtpz-data on github, you will not have this error.

[Linus Walleij]

Fixed in git version.

[Anonymous]

where i can get this git version, i have the same problem too

[Anonymous]

I have the same problem too (diasalm@yahoo.com.br)

[Anonymous]

I have the same problem. What file was left out of the build? I'm trying to build 1.1.8 from source and I get the same error.

How was the problem fixed? Is there a workaround? Please? Anyone?

[Marcus Meissner]

the 1.1.9 release should no longer print it

[Anonymous]

this bug still exists. It is affecting me right now. Why is this listed as closed?

[Marcus Meissner]

if you have correctly upgraded to 1.1.9 it should have gone. If it is still there, probably your distributions libmtp is still being used.

[Fergus Ray-Murray]

I seem to be on 1.1-4.1, thanks to apt-get in Linux Mint 17.2. Not sure what steps need to be taken, where, to get this fixed?

On the bright side, by making the configuration file using the link provided by Alex Franchuk above, I was able to remove the error message in question. Now it just says 'No raw devices found', which I'm almost sure counts as progress.

[Marcus Meissner]

open a ticket with Mint.

[Anonymous]

oh.gosh.

Thanks Alex Franchuk. The link you posted (https://github.com/kbhomes/libmtp-zune) is the solution... I compiled libmtp my self with these steps (maybe is usefull for someone):
From inside libmtp directory I canged the priviledged from the inner files:
sudo chmod 777 -R /path_to_directory
After that I used:
sh autogen.sh
to generate the install files;
After that (the c++ builder - gcc, gcc++... with dependencies should be installed):
./configure
After that:
make
And finally:
sudo make install
That should solve the problem. At least for me it solved it.

[Anonymous]

this solved for may case

[Anonymous]

It worked for me, at last! However, I had to install a couple of files. Here's what I did:

after "sudo chmod 777 -R /path_to_directory":

cd <path_to_directory>

sudo apt-get install libtool
sudo apt-get install automake

then...
sudo ./configure
sudo make
sudo make install

Then it worked. Thanks a lot!

@Alex Franchuk
In your Link is no mtpz-data, just an mtpz.md
I found this Link in the md: http://www.sajidanwar.me/
So i built libmtp with --disable-mtpz

How i did it:
Created a temporary directory
mkdir ~/tmp
cd ~/tmp
Got my Files
wget -nc https://sourceforge.net/projects/libmtp/files/libmtp/1.1.11/libmtp-1.1.11.tar.gz
Unpacked tar
tar xvf libmtp-1.1.11.tar.gz
cd libmtp-1.1.11
Compiled
./configure --prefix=/usr --disable-mtpz
make
sudo make install
Copied the 69-libmtp.rules to the right place
sudo cp 69-libmtp.rules /etc/udev/rules.d
Clean up
cd /; rm -r ~/tmp

So far still

Unable to open ~/.mtpz-data for reading, MTPZ disabled.Listing raw device(s)

But jmtpfs works.
