When installing on Ubuntu, should we use the latest release or the least "stable" release

[Jonathan salas]

Hello,

     I'm attempting to run Orthanc in the latest "LTS" version of Ubuntu in a VM Virtualbox and I'm a little new to working within linux.

As per this link I noticed that 1.5.6+dfsg-1 is the latest release but is marked as a "testing" build. As per instructions from Jodogne found here I installed Orthanc using # sudo apt-get install orthanc 

This downloaded and installed 1.3.1 on my machine and now I'm wondering if I'm running the correct version?

I'm also running 1.5.6 on a windows machine and am now wondering if I should be downgrading to a "stable" build for safety purposes.

2 solutions: 

- use Docker so you can always select the version you want.

- if you want to stay native, replace the Orthanc executables that have been installed by the ubuntu package (including .so from the plugins) by the Latest LSB releases (http://lsb.orthanc-server.com/).

I'm still not clear on which version I "should" be using though?

Dear Alain,

I tried to replace my ubuntu binaries but it doesnt work. (originally Orthanc was installed by apt-get)

I have a segmentation fault error when I try to run the last lsb package in Ubuntu Server Bionic (by the way the file are very different 2Mb vs 41Mb, I guess this is due to differences in library compilation)

Did you succeed to upgrade Orthanc this way ?

I tried to ask for a backport but I doubt I will get an answer (https://bugs.launchpad.net/bionic-backports/+bug/1819762)

Best regards,

Salim

Just like any other software, you "should" always be using the latest available version:

I’m new to Ubuntu so please forgive me if this is an ignorant question but is there any way so make it such that I could use # sudo apt-get install orthanc to get the latest available version?

[Alain Mazy]

Hi Salim,

We've done many updates this way on Debian.  On Ubuntu, I just tried this small test (inside a Docker container because I did not want to create a new VM):

FROM ubuntu:18.04

RUN apt-get update

RUN apt-get -y install orthanc wget

RUN Orthanc --version

# it displays 1.3.1

RUN wget http://lsb.orthanc-server.com/orthanc/1.5.6/Orthanc -O /usr/sbin/Orthanc

RUN Orthanc --version

# it displays 1.5.6

It might be repeated for each plugin but, in the end, it shall work.

[Alain Mazy]

You can't get the latest version this way because the ubuntu package is not up-to-date.  So you should either use Docker or replace the Orthanc executables with the LSB releases.

[Sébastien Jodogne]

Hello,

The 2MB vs 41MB size is due to the fact that Orthanc >= 1.5.5 features support for Asian encodings, which necessitates to ship large data arrays within the Orthanc binaries.

I confirm that the LSB binaries do not work properly on Docker running Ubuntu 18.04:

$ sudo docker run -i -t --rm --entrypoint=bash ubuntu:18.04

# apt-get update && apt-get install -y wget

# wget http://lsb.orthanc-server.com/orthanc/1.5.6/Orthanc

# chmod +x ./Orthanc

# ./Orthanc

Segmentation fault (core dumped)

However, the same binaries run fine on Docker with Ubuntu 16.04. This might possibly be a bug within the Linux Standard Base compiler, that is based on an old version of gcc (4.8).

As a consequence, until this issue is solved, please replace Ubuntu Bionic (18.04) by Ubuntu Xenial (16.04).

Thanks Sebastien and Alain for your answers,

For now I changed my idea to work with the standalone app and i'm exploring the Docker install.

I think I will land with some questions about the best strategy to setup my server, but I still have to make some testing and enhance my technichal knowldge to ask the good questions,

Best regards,

Salim

Turned out that the culprit is missing "/etc/localtime" file, that is installed by default on Ubuntu 16.04, but not on Ubuntu 18.04.

Installing the "tzdata" package solves the issue. For instance:

$ sudo docker run -i -t --rm --entrypoint=bash ubuntu:18.04

# apt-get update && apt-get install -y wget tzdata
