SSH public key validation error (500)

[hvisage]

I'm bumping my head against this problem where I need to add several keys for containers at creation time, but keep getting the above error on PVE 7.4 when doing it via the WebUI/GUI interface.

What is the expression/criteria to match or make it work?

Is it acctually supported? as it seems to be pulling the file into the ssk key dialog field where new lines seems to be "lost"?

Yes it works. The gui presentation is a bit limited but if the source file is in a good format (key per line) with appropriate ssh key format, then it works.
Try a key at a time, then two. See if you can reduce the problem to problematic line. Generate a few new test keys. At last - post public keys in the forum, perhaps someone will spot an issue. Other than that, if you are sure that the source file is good, the keys are correct and you dont want to post your keys - inform the developers directly. Its software, so bugs are possible.

hmmm... seems to also botch the authorized_keys when I do find a "valid" multiple keys pub file:

I think you found a bug. It seems you are correct the UI strips /n on which further functions rely to validate the file.
You can use "pct" CLI to create CT with multi-key ssh right now.
You should file a bug here https://pve.proxmox.com/pve-docs/getting-help-plain.html
