ghostwriter // "Running as root without --no-sandbox is not supported"(solved)

[Cachorrito]

I am new to Puppy and run into some problems with installing an app I had used before on regular Debian without any issues—so I guess, it might be a "newbie on Puppy"-problem;)

1) I am on BookwormPup64 10.0.10 and have installed Ghostwriter https://ghostwriter.kde.org/ plus the required packages (e.g., Pandoc) via Synaptic.

2) While the app does show in the menu, it does not launch. When I try to run it as root, I get:

Code: Select all

# sudo ghostwriter
Using pandoc version 2.17.1.1
Using multimarkdown version 1.35
Using cmark version 0.30.2
[20905:20905:0322/182340.411027:ERROR:zygote_host_impl_linux.cc(90)] Running as root without --no-sandbox is not supported. See https://crbug.com/638180.

The link provided in the error msg, does not help (at least for me)

3) Then I tried to run the app as non-root user: Now ghostwriter is running, but I can't save files due to missing permissions. The cli output:

Code: Select all

# su spot
# ghostwriter
QStandardPaths: runtime directory '/tmp/runtime-root' is not owned by UID 502, but a directory permissions 0700 owned by UID 0 GID 0
Failed to create /root/.cache for shader cache (Permission denied)---disabling.

[22365:22386:0322/182557.350500:ERROR:shader_disk_cache.cc(606)] Shader Cache Creation failed: -2

Any ideas?

Have you tried:

Code: Select all

ghostwriter --no-sandbox

Have you tried:

Code: Select all

ghostwriter --no-sandbox

Yes, I did:

Code: Select all

ghostwriter: Unknown option 'no-sandbox'

@Cachorrito

You could try running ghostwriter as a restricted user in the Puppy Spot environment.

run-as-spot ghostwriter

Ghostwriter should launch successfully and documents will be saved with correct permissions in the /root/spot/Documents folder.

There seems to be an issue with failed auto-backup of saved ghostwriter documents, but auto-backup can be disabled in Preferences.

If this works for you, consider editing the Exec line of /usr/share/applications/ghostwriter.desktop, so ghostwriter will open successfully from the menu.

Exec=run-as-spot ghostwriter %f

To confirm above information works.

Installed ghostwriter by using Synaptic Package Manager.

Let it install whatever other stuff it also found needed.

Had to edit the file ghostwriter.desktop in location /usr/share/applications/ adding run-as-spot to exec=

To edit the file left click on it and it will open in a text editor.

Make edit and save the change.

Should start from menu ->Document ->ghostwriter

This is a normal requirement for programs that do not like to have root user run them.

Look in menu ->Help ->About root (administrator) and spot

This explains about spot user operation.

Code: Select all

ghostwriter --no-sandbox

Does indeed work for me.

Thanks for all replies. The run-as-spot edit did the trick
