Minio doesn't allow root user change

Question

I am trying to change use a different password on mini. I followed the guide. First time around executed it via sudo (since the guide uses /data folder) and then cleaned everything up (deleted /data as well as .minio dir).

Trying to set the variables...

export MINIO_ROOT_USER=otheruser
export MINIO_ROOT_PASSWORD=otherpass

./minio server /home/debian/data/

... only results in Invalid Credentials message. Same case for...

export MINIO_ROOT_USER=otheruser
export MINIO_ROOT_PASSWORD=otherpass
export MINIO_ROOT_USER_OLD=minioadmin
export MINIO_ROOT_PASSWORD_OLD=minioadmin
./minio server /home/debian/data/

...which also gives the same result. If i set both variables to minioadmin, it all works.

How do i change the admin account?

EDIT 1:

I also tried executing everything with sudo -E. Doing so, for both options, does nothing (throws same exception).

EDIT 2:

I have tried clean new install of whole machine. Even with that and without ever using sudo this time, it doesn't work.

#minio version go1.16

#secret key must be minimum 8 or more characters long

touch runminio.sh

vi runminio.sh:

export MINIO_ROOT_USER=otheruser
export MINIO_ROOT_PASSWORD=otherpass
nohup /usr/local/minio server /home/minio/data > /home/minio/minio.log 2>&1&

./runminio.sh
