What are you fixing here? sudo sudo … is supposed to work just fine.

Suggested change

	sudo su -u postgres openqa-setup-db your_username openqa-local
	sudo -u postgres openqa-setup-db your_username openqa-local

or (if really needed)

Suggested change

	sudo su -u postgres openqa-setup-db your_username openqa-local
	sudo su - postgres openqa-setup-db your_username openqa-local

su does not have -u option

personally I use sudo -u postgres and I would have remove the su but it is another reference which give the command as sudo su -u postgres. https://github.com/os-autoinst/openQA/pull/6665/files#diff-4d6d1050121df87969e32770abd50500a1fbda9f136db4fbb374fe05a236f2c2R393

the reference you are mentioning gives sudo su - postgres, the missing u is not a typo 😉

[Wabri]

why not just using the sudo -u postgres?

[Martchus]

The sudo sudo -u postgres command is useful if you're not already root. If you just run sudo -u postgres as your normal user you might be prompted for the password of the postgres user (depending on the sudo configuration) which you probably wouldn't know.

sudo sudo

ok. I didnt try it. As I said in another comment I personally use sudo -u postgres and I thought this sudo sudo meant to be the same as https://github.com/os-autoinst/openQA/pull/6665/files#diff-4d6d1050121df87969e32770abd50500a1fbda9f136db4fbb374fe05a236f2c2R393
