Error during sdk installation

Platform Development

Trying to install Sailfish SDK version 3.7.4 on Ubuntu 20.04
During installation I’m selecting docker,
this is the error I’m getting:

Error during installation process (org.merproject.mersdk):
Execution failed (Unexpected exit code: 1): “/usr/bin/docker build --tag sailfish-sdk-build-engine /home/lolek/SailfishOS/mersdk”

There’s also this in the log:

Step 1/5 : FROM scratch

—>
Step 2/5 : ADD sailfish.tar /

failed to copy files: Error processing tar file(exit status 1): lchown /etc/mersdk: invalid argument

Sending build context to Docker daemon 4.661GB

Step 1/5 : FROM scratch

—>
Step 2/5 : ADD sailfish.tar /

failed to copy files: Error processing tar file(exit status 1): lchown /etc/mersdk: invalid argument

Any ideas?

Are you perhaps trying to use docker in rootless mode? Or perhaps really using podman instead of docker?

yes that’s it

Bump, do you maybe have any news regarding my situation?
I’ll repeat, yes I’m using docker in rootless mode.

No news to report. Docker is only supported in the normal “with root” mode.

Ok, I got it working with “normal docker” but it wasn’t straight forward.
Once I deleted all the SDK installation I started again and had problems getting project to work. Also the qtcreator was getting segfaults.
What helped was to wipe out SDK installation again and also the config which is inside of the

$HOME/.config/SailfishSDK

then install it again.
After that it seems it’s working properly.
Leaving it for others in case they’d have some problems.

I got the same issue. Running the command manually and clicking Ignore in the wizard worked on my side.

Following @pherjung advice I also copied the command and ran it in a separate terminal. Unfortunately it fails:

Should I just “ignore”?

Before doing that you should figure out how to make docker not freak out because of the existing /etc/resolv.conf. And then you should run the failed chown command in the container. After that you can ignore.

I did install sdk two weeks ago on lin mint
Headless not supported is in the docs.
The first installation failed with some download issues. Uninstalled, deleted the sailfOS Folder, second try . Done.
Docker is way better then virtual box that i was using the last 10 years.

I ve felt a bit helpless with the link to official docker doc but how else do you want to keep that accurate.
And actually during docker install i had the download issue too.

It’s a symlink on my Kubuntu 22.04, maybe that’s the issue
