A recent slack update is not allowing me to update .tar.gz files and I do not have access to vendor.replicated.com or any other means, how can I upload this via Slack?
Generally we prefer support bundle be uploaded via vendor.replicated.com or you can send it to support@replicated.com which will open a ticket. But if the bundle is too big for email or you do not have access to upload it via usual means, uploading via slack is okay.
To work around this, rezip the .tar.gz into a .zip file and Slack should allow you to upload that.
