Re: Another problem installing GNUstep using gnustep-web-install-dev

Hi Greg,

I decided to start over from a clean Ubuntu, e.g. I rolled back all my changes to my Ubuntu-VM using the snapshot of it I did after installing Ubuntu. Here is what I did:

——8<—— snip ——

# needed for running gnustep-web-install-dev from web

sudo apt-get install curl

sudo apt-get install git

# needed for github access

cd ~/.ssh

touch id_rsa

vi id_rsa

touch id_rsa.pub

vi id_rsa.pub

chmod 600 ~/.ssh/*

ssh-add ~/.ssh/id_rsa

# set root user password. Currently needed for gnustep-web-install-dev

sudo su -c passwd

# optional: create shared folder between host and guest (GNUstep-shared)

sudo adduser lars vboxsf

sudo chmod 755 GNUstep-shared

cd ~/GNUstep-shared/

# finally install GNUstep

curl https://raw.githubusercontent.com/gnustep/tools-scripts/master/gnustep-web-install-dev | bash

——8<—— snap ——

However, this time the gnustep-web-install-dev suddenly stopped without doing all it should. Have a look at the attached output of running the script:

<GNUstep-Ubuntu-24.04-install-attempt.2.txt>

Do you have any idea what was going wrong this time?

Kind regards,

Lars

Hi Greg,

I did some more research and found out this:

„What Is the Ubuntu Default Root Password in Linux? In Ubuntu Linux, the root account is locked by default, meaning there is no default root password, and direct login as root or using the 'su' command to become the root user is not possible.“ (see https://host-world.com/ubuntu-default-root-password-default-ubuntu-password-explained#:~:text=What%20Is%20the%20Ubuntu%20Default,root%20user%20is%20not%20possible. )

So this:

su -c 'echo "${USER} ALL=(ALL:ALL) ALL" > /etc/sudoers.d/${USER}‘

from setup-linux will never work on Ubuntu since there is no root password set anyway.

I think the whole setup-linux is not needed on Ubuntu since it comes with sudo enabled after a default install.

However, I also researched on how to pass a password to sudo and created this test.sh:

————

#!/bin/bash

echo "welcome!"

read -sp 'Your password:' PASSWORD

echo $PASSWORD | sudo -S whoami

————

which prints „root“ on my Ubuntu

Does all this make sense?

Kind regards,

Lars

Hi Greg,

I am using ubuntu-24.04.1-desktop-amd64.iso from https://ubuntu.com/download/desktop in VirtualBox

sudo is there:

lars@Ubuntu-2404-VirtualBox:~$ sudo whoami

[sudo] password for lars:

root

lars@Ubuntu-2404-VirtualBox:~$

The setup-linux script „asks“ for a password but doesn’t wait for me to enter it. It continues instead saying „su: Authentication failure“:

sudo command is already present.
Adding lars to sudoers...
Please enter the root user's password.

Password: su: Authentication failure

Kind regards,

Lars

What particular version of Ubuntu are you using? I suspect it's missing sudo or another command needed to install.

Hi dear GNUsteppers,

today I tried installing GNUstep on a fresh Ubuntu 24.04 copy.

For this I used the command found on the GNUstep website:

curl https://raw.githubusercontent.com/gnustep/tools-scripts/master/gnustep-web-install-dev | bash

However the script failed to read my password, here is the output of the script:

lars@Ubuntu-2404-VirtualBox:~$ curl https://raw.githubusercontent.com/gnustep/tools-scripts/master/gnustep-web-install-dev | bash

IMPORTANT!
You must update your .ssh directory so it contains your github ssh key

Begin setup for linux
sudo command is already present.
Adding lars to sudoers...
Please enter the root user's password.

Done…

It looks like the script isn’t waiting for me to enter the password. I had a look what is going on and found this script:

setup-linux:

#!/bin/sh

export USER=`whoami`
if [ ! -e /usr/bin/sudo ]; then
echo "Installing sudo..."
if [ -e /usr/bin/apt ]; then
su -c "apt install sudo"
else
su -c "rpm install sudo"
fi
else
echo "sudo command is already present."
fi

if [ ! -e /etc/sudoers.d/${USER} ]; then
echo "Adding ${USER} to sudoers..."
echo "Please enter the root user's password."
su -c 'echo "${USER} ALL=(ALL:ALL) ALL" > /etc/sudoers.d/${USER}'
else
echo "${USER} is already a member of sudo users."
fi

In this script I see the line:

echo "Please enter the root user's password.“

followed by su -c which I think needs the password.

However, the script isn’t waiting for me to enter the password. I am not that of an expert in bash, but shouldn’t be there some sort of „read“ in between both commands? Or I am missing something here?

Kind regards,

Lars
