Docker is installed but isn't running on Ubuntu 22.04 about dangerzone HOT 11 CLOSED

Hm, in Ubuntu 22.04 you don't actually need Docker. You only need podman, which is installed as a dependency of Dangerzone. Probably an error message of ours threw you off, sorry for that.

Could you please run dangerzone-cli <document>, where <document> is the path of a document you want to convert, and write here the error you're seeing? I believe Podman is somehow misconfigured, and that's why Dangerzone shows this (bad) error message.

from dangerzone.

Hi! Thanks a lot for your quick response. The initial mistake was that I need to run it with root privileges but the menu access does it as my standard user. But when I run it with sudo, I get this error:
sudo dangerzone-cli Data\ Structures\ and\ Algorithms\ with\ Python[Undergraduate\ Topics\ in\ Computer\ Science.pdf

from dangerzone.

The initial mistake was that I need to run it with root privileges but the menu access does it as my standard user.

Actually, that's not a mistake! It's best to run Dangerzone as a non-root user, as most GUI applications. Could you perhaps run it instead as your regular user and post the logs here?

Also, let's check for some common reasons for failures:

1. Is your user ID 1000? You can check with id. The reason I'm asking is due to #624.

2. Does podman info return any error?

3. What's the result of:

   /usr/bin/podman run --network none -u dangerzone --log-driver none --security-opt no-new-privileges --userns keep-id --cap-drop all --rm -i dangerzone.rocks/dangerzone echo "Works!"

Hello Sir!
Yes, my id is 1000. Is the first user created on my system. I need to run dangerzone and podman with root privileges since my regular user (id = 1000) doesn't have writing permissions on those folders (where podman tries to create a container for dangerzone or the code you provided). So, the result for what you suggested is:
Error: error creating tmpdir: mkdir /run/user/1001: permission denied
The result when I try to use dangerzone-cli as a regular user (id = 1000):

(I edited the above code blocks in your comment for clarity. When pasting code, prefer to use Markdown's triple ticks (```)

Yes, my id is 1000. Is the first user created on my system. I need to run dangerzone and podman with root privileges since my regular user (id = 1000) doesn't have writing permissions on those folders (where podman tries to create a container for dangerzone or the code you provided). So, the result for what you suggested is:
Error: error creating tmpdir: mkdir /run/user/1001: permission denied

And yet, Podman attempts to create a temporary directory for a different user (1001). This rings a bell (#620 (comment)).

Let's dig deeper. Can you write down the output of the following commands?

id
env | grep -e 'TEMP\|TMP'
podman info

As for running Dangerzone as root, it's a use case that's unfortunately not supported (and to be frank, it would be best avoided). You may make it work, but our best bet is actually fixing your Podman installation, so that you can run Dangerzone as your regular user.

from dangerzone.

id

Result:
uid=1000(francisco) gid=1000(francisco) groups=1000(francisco),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),122(lpadmin),135(lxd),136(sambashare),141(vboxusers)
for:

env | grep -e 'TEMP\|TMP'

Result:
nothing at all.
for

podman info

Result:
Error: error creating tmpdir: mkdir /run/user/1001: permission denied
In my system, no user has id = 1001 by the way.

Thanks a lot for your help :)

from dangerzone.

Cool, thanks for the output. Can I ask you to share one more?

env | grep XDG_RUNTIME_DIR

from dangerzone.

Sure! Here it is:

XDG_RUNTIME_DIR=/run/user/1000

from dangerzone.

Sigh, I'm out of ideas. It seems to me as an issue with your Podman installation. The fact that podman info cannot even run, or that it refers to /run/user/1001 is a sign that something is wrong there.

Searching for this issue on the internet, I found a similar report. If you have recently switched your home directory, then Podman probably has kept some state there. In that case, it's best to nuke the Podman configuration.

from dangerzone.

It works!
I followed your last instructions: to nuke the podman's installation. I just didn't know how to until I found this post: containers/podman#5049. Specifically this little action:

rf ~/.local/share/containers/

Thanks a lot for your help and for this great software :)

from dangerzone.

Oh, that's great! I'm happy that you got it resolved. I'll close this issue now, but feel free to create a new one, if you stumble onto something else.
