Terminal emulator not working

[w1bsb]

Running Debian 9.5 with lxd installed via snap. Installed both master and development branch, no errors reported. Everything appears to work except the "terminal" emulator when I try to open a terminal for a container. I get the new browser tab, and a black screen with a blinking cursor but it never shows anything. I am able to access the container using the command line and opening a bash shell to it, or with ssh once installed inside the container.

Hi @w1bsb

I have not tried it on Debian so I can't say its on OS specific issue/bug. Have you had a chance to try it out on Ubuntu 16 or 18 as a comparison? Are there any errors in the log that you can share?

Some here on Ubuntu 18, this is the log report

I just receive a black terminal window that opens up in a new tab. Just a blinking cursor and I unable to do any input.

Any advice how I can find the logs or how to correct this issue?

I came a crossed this post looking into the same issue on ubuntu 18.04 using the snap version of lxd

Terminal window is working when lxdui started on raw system
Terminal window is not working when lxdui started inside docker container with -p 15151:15151.
Terminal window is not working even when lxdui started inside docker container with --net=host.

The reason that it works sometimes and not others is that in the argument for the shell executable is set to a static value. Depending on the container it may or may not have the shell environment that terminal app is expecting. If you install Bash inside of your container you should be able to use it then. Give that a try and let us know how you make out. Regards, Tony Hajdari
