Error during sdk installation

Platform Development
#1

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

Any ideas?

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

#3

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.
