How to reproduce ?

[nmartinho]

I just build-it following the instructions.

My system: Debian wheezy - kernel 3.3.0+ armv7l

Hi,

Same problem with the binary under F19

Sarath, I had the same error message and found this issue from google. For me the issue was having a special character in my password "%" . It was the last character of the password but I didn't test whether or not that was necessary for reproduction. Normal alphanumeric password works find. Hope that helps! thanks for the tool.

[derabbink]

Same issue here. I don't have any out-of-the-ordinary characters in my config; just built it from scratch and used a config file like the example one in README.md.

My system is ubuntu 14.04 x86_64

[ml-]

Had similar problem, seems to be a bug in golang. Try compiling golang from sourcecode and try again.

[yayscripting]

Got something similar but it happened randomly. I uploaded around 5000 photos after this happened so I don't know why.

I builded the binary myself from source (darwin_amd64).

Any clue why this happens? I have tried changing folders

I get this too.

It appeared out-of-the-blue and first I suspected that there were some go runtime update that I didn't notice that broke it. However, there wasn't. I updated to golang 1.3 (OpenSUSE-13.1, 64bit) and recompiled megacmd. Same issue persists not only with uploads but also e.g. list. Every time.

[rinne]

Stack trace shows

github.com/t3rm1n4l/go-mega.blockDecrypt(0x0, 0x0, ...

It smells like wrong, since its:

func blockDecrypt(blk cipher.Block, dst, src []byte)

[t3rm1n4l]

Could you list out some steps on how to reproduce this problem ?

[t3rm1n4l]

Could you try latest code ?

[pafnow]

I tried with the lastest code as of yesterday and the issue still happen randomly... Any thoughts?

[alvgarci]

Same issue here (OSX 10.10.2), just trying to list some files... any clue?

[alvgarci]

(of course last megacmd code)
