split fails: error: write /dev/stdout: permission denied about konfig

[jglick]

Can you export NDEBUG=y and show the log output?

Does not produce any additional output.

It could very well be a snap problem

Indeed it seems that way—works when using a manually downloaded kubectl. This snap uses “classic confinement”, which generally means it should behave like a plain package (I have not encountered any permission-related errors in any other usage), but maybe there is some subtle difference here.

This is a snap problem. There's nothing I can do to konfig to improve this situation.
FWIW, this seems related: moby/moby#31243 (comment)

this could be related to an issue of snap: https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/1849753

Hmm.. curious. Can you export NDEBUG=y and show the log output?
It could very well be a snap problem which I won't be able to reproduce, so if you want to investigate further that would be great.

Also seeing this with the snap version of kubectl. However I get it with the import command:

kubectl konfig import -s kubeconf2.yaml 
error: write /dev/stdout: permission denied

[jglick]

What code here is actually trying to use /dev/stdout? I do not see any in this repo. Is it something being called by this script? Most uses of /dev/stdout can be replaced (a bit awkwardly) with temp files.

[jglick]

Indeed. https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/1849753/comments/26 suggests a workaround: replace

kubectl … > "$tmpcfg"

with the rather cryptic

kubectl … > >(cat > "$tmpcfg")
