Hmm, that's an odd one. What operating system are you using and what does running ls /tmp/tmpp_7xwf_a
show?
I am running ubuntu and the /tmp/tmpp_7xwf_a is not there. Below is the output I got from the running the ls and lsb_release commands in the terminal. Thanks for your help.

Thanks for that information. You seem to be using the Snap version of Docker, which appears to have the limitation that it cannot access any files outside $HOME
. The solution in this case is to uninstall the Snap version of Docker (sudo snap remove docker
) and to re-install Docker via the official installation instructions for Ubuntu.
The reason we use /tmp
is that everything in there is automatically deleted on reboot. This is useful to the CLI because occasionally we leave behind some files which are owned by root and can therefore not be deleted by the CLI itself.
Yes, that worked. Thanks!!!
Below is the verbose output I am getting when I try to run the lean local backtest command.
Can you let me know what I'm doing wrong? Thanks.
