Cubic

running cubic in docker image

Asked by Diethard Seiferth

When I run cubic in a docker image, it reports following error:

  • Execute synchronously.................. mount-iso "/home/xxx/iso_src/x
                                            ubuntu-20.04.2.0-desktop-amd64.iso"
                                            "/home/xxx/iso_target/source-
                                            disk" "1011" "1011"
  • The process id is...................... 2047
  • The result is.......................... Error getting authority: Error
                                            initializing authority: Could not
                                            connect: No such file or directory
  • The exit status, signal status is...... 127, None
...
 • Is mounted?............................ False

But I can mount manually, for e.g.:

$ mkdir iso_target/source-disk
$ sudo mount -r -t iso9660 -o loop /home/xxx/iso_src/xubuntu-20.04.2.0-desktop-amd64.iso /home/xxx/iso_target/source-disk

What permissions does cubic need?

Are you able to mount anything in your docker image using the command line (i.e. not using Cubic)?

I didn't read the second part of your question correctly-- I see that you can mount the location manually.

Check if dbus is running:

    $ service dbus status

If it is not running, start it:

    $ sudo service dbus start

Then launch Cubic.

How do you start your docker container?
I may be able to try it on my end to see what is going on.

Also, based on your log output, your locale doesn't seem right.
You need to have UTF-8 support for Cubic and for .Cubic's terminal environment.
(If it is not available in your host environment (docker) it may not be available in the Cubic Terminal).

I tried in another ssh terminal with utf8 installed, but the same.
