[SOLVED] fstrim command not found

Hello everyone,

I have installed Devuan Daedalus 5.0.1.
Now I wanted to optimize my SSD and ran the following command manually, both as user and root:

fstrim -v /

Whether as user or root, I get the following error message:

bash: fstrim: command not found

I have run this command hundreds of times on various distros.
Does anyone have an idea what I am doing wrong?

Many thanks in advance.

How did you try to get root access? A simple su or a su -? Give the

~$ su - 

a try.

Hi rolfie,

I had only tried it with a simple su.
Your tip with

su -

solved my problem.

What is the difference between su and su -?

The path. Thats why you get command not found.

There was a change in Debian some releases ago that moved the su command into a different package and changed the behaviour. I think there is a hint in the Buster/Beowulf release notes.

I come from Arch distributions, so I still have a lot to learn about Debian / Devuan.

Thanks again for your help.
