Error in updating

[nopria]

Running docker-slim update I get the following output:

docker-slim[update]: info=version local=1.38.0 current=1.39.0
docker-slim[update]: state=update.download.started
docker-slim[update]: state=update.download.completed

I'm using WSL2 on Windows 10.

Sounds like a path permission problem... Can you try enabling the debug mode to see more info ( docker-slim --debug update or even docker-slim --log-level=trace update )

[nopria]

Sure, here is the result:

Finally I managed to update with the following workaround procedure:

• manually delete the content of directory \tmp\docker-slim-state\.docker-slim-state\releases
• update using super user rights with sudo docker-slim update

[kcq]

Thank you for your investigation here! Using sudo is a good workaround for the permission problem. Need to revisit the updater logic to check if the binary update can be done in a different way, but if writing to the /usr/local/bin directory requires extra permissions it might be tricky to do it without sudo.

[nopria]

Unfortunately the above workaround does not work anymore. Now I'm using WSL2 on Windows 11.

Here is the log of failing update without sudo:

Any idea on what is happening and what is the original sin?

[kcq]

This looks like a download related error (could be networking related or could be something in the download logic)... I'll try to repro the condition and I'll share my findings

[nopria]

I ran again the update and this time there was no "error downloading release package" message, so I report again the logs using sudo, without and with --log-level=trace option:
