Hi there,
I am trying to install Virtuoso on Ubuntu Server 24.04. I started by following this OpenLink guide, which resulted in a 404 error. In the mail-list I am told to install the pre-compiled binaries directly. However, that version does not even start.
Where can I find an install guide for Ubuntu? Or Linux in general?
Thank you.
Hi Luis,
I have flagged the page you mentioned to be reviewed by our documentation team.
Note that the virtuoso-opensource package from Ubuntu is an old version 7.2.5 from 2018, so i don’t recommend using that.
You can use the following instructions to get going with the latest release:
$ cd /tmp
$ wget virtuoso-opensource.x86_64-generic_glibc25-linux-gnu.tar.gz
home directory or somewhere like /opt or /usr/local. Make sure you put it on a filesystem with plenty of space for the database. $ cd /opt
$ tar xvfz /tmp/virtuoso-opensource.x86_64-generic_glibc25-linux-gnu.tar.gz
virtuoso-opensource/database directory $ cd virtuoso-opensource/database
virtuoso.ini.sample file into virtuoso.ini $ ls
virtuoso.ini.sample
$ mv virtuoso.ini.sample virtuoso.ini
../bin/virtuoso-t -f to start the database in foreground mode. In the output you will see various plugins being loaded, the database being created and the Conductor VAD package being installed, something like this: $ ../bin/virtuoso-t -f

You should now be able to use the following endpoints:
Note that this form of installation leaves the dba and dav users with a default password, so i recommend you first point your browser to the conductor at http://localhost:8890/conductor and:
Also change the password of the dav user in the same way.
Hi @PvK, thank you for the prompt reply. As I wrote initially, that version is not able to start, a bit of log is below.
Indeed I urge you to update the install guide. Also consider that version 7.2.5 is being offered of the Ubuntu multiverse.
Regards.

The reason why virtuoso-t -fd cannot find the virtuoso.ini file is that you are in the virtuoso-opensource directory, and not in the virtuoso-opensource/database directory.
By default we use a virtuoso.ini that uses relative paths for the database and related files, so users can install the package anywhere on their system.
Please run:
$ cd database
$ ../bin/virtuoso-t -fd
Thank you again @PvK, that was indeed the issue. I would recommend transforming your original message (with the added path reminder) into an install guide for Linux.
Regards.
