[I know this is duplicate but all the answers here didn't work for me.]

I am a life-long Windows user who has migrated to Ubuntu since 5 weeks.

I am trying to copy files to my Android tablet and for two days I am getting this error: libmtp error: could not send object, and after I tried some solutions on and off this website, the error trasformed to libmtp error: Unknown error.

I must say, however, that copying file from my tablet to my Ubuntu works quite fine.

Can any one PLEASE help?

    I apologize if this seems obvious (it wasn't to me!): Did you turn on your android device and unlock the screen (and make sure it stayed unlocked) before moving the files?

    @Rabbit, I've always turned it on and unlocked itm but never left it unlocked, and VOILA, it worked! I now can never know if one of the solutions I tried worked or it was my fault from the beginning!

    @Rabbit maybe you could add that as an answer since it seemed to be the trick. Or MuAnwar96 you can add the answer yourself (in the answer section below)

    Cool beans! I'm so glad I could help (if indeed it was that suggestion that helped in the end). I've added it as an answer.

Try turning on your Android device and unlocking the screen (and make sure it stays unlocked / unlock it again) before moving the files.

    This fails to work in my case, the error persists. Any other solution, please?

Try with android-file-transfer. Take a look to the latest AppImage (at end-2019).
