My Teams current version is the same 1.4.00.7556, but yesterday i have installed the update.

Earlier that error was with all the file names latin and local.

But now you are right, latin filename is Ok, local has a problem.

Now it is definitely encoding issue and has to be fixed.

Jimmy, seems i have localized the problem. Trying to summarize.

I installed MS Teams under 1st main admin account with sudo command: sudo apt install teams

Then i tried to upload *.ppt file and everything was fine. No "file is empty" error message.

Then i relogged to the 2nd user account (not admin), which is mostly using MS Teams application, and then received the same error message "MS Teams: The file <....>.ppt Upload failed - file is empty!"

In both cases i have tried to upload files from user home Documents folders, so i think there was no file access questions.

Also i cant grant admin access to 2nd account.

Please let me know what to do next.

thanks.

Hi @JimmyYang-MSFT
any update?

@JimmyYang-MSFT

Hi Jimmy, i did what you suggested and it was no effect.

Teams raised the same error: "file is empty"

If you scroll down my post you may see the another person having the same error - OstrolkAdam-8411.

He said that he cannot send files (error file is empty) using downloaded .DEB package microsoft teams. Sending pictures is OK.

Thats exactly the same situation as i got.

Please let me know what we can do next for resolving this issue.

Thanks,

@JimmyYang-MSFT

this web client?

https://www.microsoft.com/en-US/microsoft-teams/group-chat-software/

What browser do you use to access Teams web client from Ubuntu 20.04?

sorry, cant find folder:

~/.config/Microsoft/Microsoft\ Teams\ -\ Insiders

I have found:
~/.config/Microsoft/Microsoft Teams/...
should i delete everything there and below?

and yes, not only PDF files are not uploaded into chat. PPTX not uploaded as well. The same for DOCS. JPEG files are uploaded OK.

I think this is the right time for analyzing logs. Please let me know how to trace.

From Android phone files PDF, PPTX and other files are uploaded OK.
