How to enable SUDO on Azure Debian webapp ?

Hans Baumhardt 0

Upgraded a Azure Linux webapp from PHP8 to PHP8.3 as required by an on screen portal admin notification.

The SUDO management command no longer works in an SSH session.

-bash: sudo: command not found

Apparently PHP8.3 is now a DEBIAN Linux build which does not include SUDO.

Trying to install sudo fails:

su -

apt-get install sudo -y

E: Unable to locate package sudo

yeah, thanks Microsoft.

Hi @Hans Baumhardt
Thanks for the question and using MS Q&A platform.
It appears that your Azure Debian web app does not have sudo installed by default, which may be causing the "command not found" error. Some Azure web apps, particularly those in containerized environments, come with a limited set of pre-installed packages, and sudo might not be included.
1.Azure web apps can have restrictions on package installation. If you're in a restricted environment, installing sudo might not be possible.

2. If you have access to the root user, use su - to switch and then attempt installing sudo. However, if apt-get can't locate the package, it could indicate that your package repository is not correctly configured.

3.Ensure your package lists are up to date by running:
apt-get update

After updating, try installing sudo again:

apt-get install sudo -y

Many thanks, but this is just a repeat of exactly the lines of text I originally posted.

Is this Reddit ?
