a2enmod not working on debian (buster)

Question

Running a2enmod gives:

bash: a2enmod: command not found

I've hunted high and low and can't find any answers. Is there something I need to do/install?

You need to run the command as root. You can do this with sudo a2enmod ... — Torin, Apr 25 '19 at 19:04
I've been running the command as root and I have installed apache2. — H2ONOCK, Apr 30 '19 at 10:59

Also if you used to open your root session with "su", then after upgrading to buster make sure to use "su -" instead, otherwise some commands won't be available (including a2enmod).

This fixed it, nice one! – H2ONOCK Jul 10 '19 at 17:35
This worked for me as well. Can you explain why this fixes the issue? Thank you. – hendr1x Jul 05 '20 at 15:33

@hendr1x In Debian 10 you can su to root but if you want the most powerful features you have to go up a level by running su - instead. I hope that helps. – H2ONOCK Nov 18 '20 at 12:51
BTW This change is documented in https://wiki.debian.org/NewInBuster – HolgerJeromin Jan 09 '21 at 19:24

It's a PATH variable bug.

Try this:

apt-get install mlocate
updatedb
locate a2enmod

the output is:

/usr/sbin/a2enmod

then

 grep PATH /etc/profile


PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/sbin"
PATH="/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games"
Export PATH

As you can see, /usr/sbin in not in root $PATH

So, edit the first line to

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/sbin"

And then

# . /etc/profile

And then you are OK.

Actually /usr/sbin is the last entry in the first line. – RalfFriedl Nov 12 '19 at 18:01

the step to "edit the first line to" matches the first line. what is the difference? – Oxymoron Dec 30 '19 at 18:11

also the "As you can see, /usr/sbin is not in root $PATH" line doesn't make sense as it is in the $PATH, even in your example. – Oxymoron Dec 30 '19 at 18:12

However, I will give you a vote up because running . /etc/profile did fix my problem – Oxymoron Dec 30 '19 at 18:13
@Oxymoron thankyou . /etc/profile solve my prob. too – Márcio Rossato Jun 16 '21 at 19:53

You need to have installed apache2

sudo apt install apache2

and sudo a2enmod file

you can also do a symbolic link:

ln -s /rute/ /rute2/

He can't create a symbolic link if he's not root. And the syntax would be cd /etc/apache2/mods-enabled; ln -s ../mods-available/foo – Freddy Apr 25 '19 at 23:05
I've read that I shouldn't be doing it that way and that I should be using the a2* functions instead which is why I'm trying not to revert to doing that. – H2ONOCK Apr 30 '19 at 11:00
