"libmtp Error: Could not send object." when copying big files anywhere in the device of 40 mb or more.

[Daniel Jony Beninca]

ENVIRONMENT:
Ubuntu 15.10 64-bit

Since I updated ubuntu from 14.04 to 15.10 I started having problems with copping files bigger than 40 mb or copying several files whoso size summed are bigger than 40 mb as well.

My device is a LGG3 D885p Android 5.0.

I am a new Ubuntu user and I don’t know libmtp version, I couldn’t see the version by the command line "apt-cache policy pkgname”, or maybe I’m doing it wrong. But now, with the version 15.10, I updated the libmtp and I could see in the console that package version is more recent.

This problem happens when I copy any file fro Ubuntu (by Nautilus) to a Android device. The problem also happens when copping file by file with over 4 mb.

STEPS:
1) Connect the device to the USB port;
2) Select MTP option in your device;
3) Copy any file or folder with over 40 mb to the device;

EXPECTED RESULT:
The copy operation should succeed.

CURRENT RESULT:
An error message is presented on the desktop: "libmtp Error: Could not
send object."

I noticed that the above problem occurs in a specific directory, it has 44 mb have to send this directory to you to this problem from occurring there.

I believe this problem then occurs in earlier versions, how do I send the files that are causing error in the copy?

[Daniel Jony Beninca (danieljony)]

After more tests, I realized that the problem only occurs with the file which appears in the error message, you have 4.7 mb, so I only have to send this file to test there?

Status changed to 'Confirmed' because the bug affects multiple users.

Some estimate of when this problem will be solved, it occurs with any file, this problem is hindering me.

Ubuntu 16.04 + HTC One m8.

Could not send object when copying from local drive to phone sd card.

Today it's first time when I got this error on my phone, everything worked before I started adb server.

Workaround:

sudo killall adb

After that, 3 500MB files have been successfully copied to phone sd card.

I think, MTP driver and adb are conflicting with each other.
