Hello.

I am trying to use this script to install a Wire Guard on a Ubuntu Oracle instance, and I am getting this issue.

Can anyone help me resolve this issue?
Thank you.

You do not need to run wget as root (You should never do that) but instead run bash as root.

Wrong: sudo wget [...] && bash [...]
Correct: wget [...] && sudo bash [...]

Further Explanation:
You run two separate commands and concat them with && so sudo is not used for the whole line, but only for next command. Your && does run the right command only if the left command returns 0 or true.

Thanks @KaeTuuN for the detailed explanation.

@Nyr Maybe you could add sudo to the Install string in README.md?

No, as it depends on the particular environment. Plenty of VPS providers provide root accounts by default.

Thank you so much for your kind response.
I can run the script now.
