problem to install TPP 5.2.0

[Virginie Imbault]

Dear all,

I have a virtual machine with Ubuntu 18.04 LTS and I'm trying to install TPP 5.2.0. So I follow the wiki "TPP 5.2.0: Installing on Ubuntu 18.04 LTS". But I have an error.

when I write:

sudo chown tpp.tpp /usr/local/tpp

chown: incorrect user: "tpp.tpp"

Can I help me?

Hi Virginie, thank you for your interest in TPP.

 

That command assumes that the user account that you will be installing tpp as is called “tpp” with group “tpp”.

 

You could either create a Linux user “tpp” and a group “tpp” first, or you could replace that with the current user and group that you are installing with. Probably the current account you’re running with is fine. To find out the current username and group, try typing just:

 

id

 

Regards,

Eric

Looks like you are using the wrong separator for user and group. Just a small typo in the command.

To say user 'tpp' and group 'tpp' you have to separate them with a colon, not just a dot.

sudo chown tpp:tpp /usr/local/tpp

With the typo the computer says 'No' because she thinks that the username is 'tpp.tpp' and that one doesn't exist.
