Logs

Before gather the logs try following if that fix your issue

$ crc delete -f
$ crc cleanup
$ crc setup
$ crc start --log-level debug

Please consider posting the output of crc start --log-level debug on http://gist.github.com/ and post the link in the issue.

@jeffmaury does it behave the same in the powershell window as well or this happens only in the windows terminal app?

[gbraad]

These are escape codes (that are not interpreted correctly. And as it looks like, you are running the command prompt cmd instead of powershell.

I do not think this is a situation with a high priority, as crc status works otherwise perfectly.

[jeffmaury]

[gbraad]

@anjannath how about Mac?

[anjannath]

in macOS its fine, escape codes are being rendered properly..

[gbraad]

So it is the color. Perhaps a solution could be to make it all colorless or not for GOOS=Windows

/cc: @evidolob WDYT?

[evidolob]

Yes we could do that, perhaps, even detect if terminal supports color, and add only if terminal supports colours

[evidolob]

It seems that Windows 10(from build 10586) does support colours in terminal, we need to enable it.
We could use https://github.com/jwalton/go-supportscolor to add detection of color support on any supported OS, lib will also enable color support on windows.

@gbraad WDYT?

[cfergeau]

https://github.com/crc-org/crc/blob/main/pkg/os/terminal/terminal.go provides support to check if we run in a terminal or not, this could be extended to check if color output is supported.

[gbraad]

@evidolob add a check to see if color support is available. We can otherwise use an override structure with _windows.go if not working as expected.

Note: this is low priority and perhaps something @vyasgun can do?

[vyasgun]

/assign

When I sent a ctrl-c after the bars start printing, I could see the expected output:

The problem seems to be with the progressbar pool as I am not running into this when I am printing the progress bar independently.

fixed in #3955
