Scilab does not start on bionic and focal

[Norbert]

[Impact]
Scilab does not start. This is a regression from an OpenJDK 11 update.

SRU TEAM: please note that scilab runs OpenJDK 8 and since Bionic we have been forcing it to use OpenJDK 11 (see bug 1814133). Since the last Bionic and Focal update there have been fixes from both upstream and Debian to improve compatibility. Apart from those fixes I would like to bring additional fixes to our LTS releases and align them better with the one on Groovy (which works fine):
* improved dependencies
* appdata/desktop fixes to improve user experience
* update from 6.0.1 to 6.0.2 in Bionic

[Test Case]
On Bionic or Focal:

Steps to reproduce:
1. Install Scilab with `sudo apt-get install scilab`
2. Try to launch Scilab from terminal by using command `scilab`

Expected results:
* Scilab started normally

Actual results:
* Scilab does not start, shows the following output in the terminal:

Scilab cannot create Scilab Java Main-Class (we have not been able to find the main Scilab class. Check if the Scilab and thirdparty packages are available).

[Regression Potential]
Updating scilab fixes a regression introduced by a previous OpenJDK 11 update that prevented it from running.

* The patch that fix the library path regression OpenJDK 11 might regress on a later if OpenJDK 11 changes how the library path is loaded.

The bug is only on the GUI version, so the patch might actually introduce regressions in the CLI, but that is unlikely as, AIUI the Java bits of the codebase are completely disabled in CLI mode.

The Bionic patch might be combined with another bugfix, cf comment #35

[Hans Joachim Desserud (hjd)]

I get the same error message when attempting to start scilab on Focal.

Looks like it might be the same error occuring during build-time in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=955694

[Norbert (nrbrtx)]

Still happens even with focal-proposed.

Should be fixed before final release.

[Ubuntu QA Website (ubuntuqa)]

This bug has been reported on the Ubuntu ISO testing tracker.

A list of all reports related to this bug can be found here:

[Lesley (lesleydc)]

It also happens on bionic (again) for scilab version 6.0.1-7ubuntu1~18.04.1.

[Snark (julien-puydt)]

As openjdk was updated in Debian recently, another patch was needed to make scilab run ; I'll attach it.

[Snark (julien-puydt)]

Created attachment 5134
Patch addLibraryPath.patch against package version 6.1.0+dfsg1-2

This patch from Gilles Filippini was added to the Debian package version 6.1.0+dfsg1-2.

[Norbert (nrbrtx)]

Still happens on Focal.

[Stéphane Mottelet (mottelet)]

Is this solution backward-compatible for systems using openjdk-8 ?

[Timo Aaltonen (tjaalton)]

fixed in groovy

 scilab (6.1.0+dfsg1-2) unstable; urgency=medium
 .
   * Add new patch to avoid FTBFS with newer libxml2 (Closes: #949494).
   * Make the classpath less sensible to version changes (Closes: #892254).
   * Add new patch from Gilles Filippini to fix NullPointerException with
     openjdk >= 11.0.7-9 (Closes: #955694, #956908).
   * Add patch to the appdata file so it points to the right desktop file.

[Norbert (nrbrtx)]

Please do not forget to fix this bug from *focal* 20.04 LTS (!!!!!!).

[Norbert (nrbrtx)]

Please do not forget to fix this bug from *focal* 20.04 LTS (!!!!!!).

[Norbert (nrbrtx)]

Scilab is still broken on latest LTS release.

[Norbert (nrbrtx)]

This is really unbelievable.
Ubuntu is often used by educators. Educators use Scilab.
But the Scilab packages are broken in 18.04 LTS (bug 1884277 ), in 19.10 (EOL, bug 1877234) and in upcoming 20.04 LTS too (this bug 1870813 ).

Are you kidding?

[Matthias Klose (doko)]

Norbert, your choice of language certainly doesn't help. If you would like to help, please could prepare a SRU for scilab, see https://wiki.ubuntu.com/StableReleaseUpdates for the procedures.

[Dimitri John Ledkov (xnox)]

Works on groovy correctly, installs launches, interpreter executes commands and I can exit it.

I am very basic scilab user, and forgot everything about it since university.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Tiago Stürmer Daitx (tdaitx)]

Backporting some selected fixes from Groovy works ok on Focal.

Norbert, assuming scilab 6.1 works on Bionic, do you see or know any limitations/problems of upgrading Bionic's scilab from 6.0 to 6.1?

[Tiago Stürmer Daitx (tdaitx)]

Added bionic task. Removed java-common and openjdk-lts as being affected.

[Norbert (nrbrtx)]

@Tiago Stürmer Daitx (tdaitx)

I have tested 6.1 from Groovy on Focal - it works normally.
So backporting 6.1 to Focal is a good solution.

I'm not sure about using 6.1 packages on Bionic, can't install them directly here because of dependency problems for at least libc6.

The Scilab 6.1 itself is good.

Thank you!

[Tiago Stürmer Daitx (tdaitx)]

Norbert, thanks for the updates. The package has been uploaded to Focal and is waiting approval.

As for Bionic, I will cherry pick some patches. Scilab 6.1 introduced the fileio module which depends on std::filesystem::weakly_canonical that is only available on libstdc++-8. Bionic uses gcc/g++ 7 by default, so we are not recompiling scilab with gcc/g++ 8.

[Norbert (nrbrtx)]

Scilab is still broken on supported 18.04 LTS release. How long?

[Sylvestre Ledru (sylvestre)]

I guess this package is synchronized from Debian and not maintained in Ubuntu.

Maybe volunteer to help?

[Ian Gebbie (igebbie)]

Hi

Thanks for the feedback. Better on 20.10.

Yeah, happy to help. Maybe a pointer to the best way to start?

Cheers

Ian

[Sylvestre Ledru (sylvestre)]

Karl would be happy to see you helping ;)

[Stéphane Mottelet (mottelet)]

Bonsoir Sylvestre,

Il va falloir que tu m'explique ce que je peux faire de mon côté car
c'est plutôt Clément qui maitrise le build sous Linux (moi c'est sous
macOS, et les problèmes sont disons... différents mais tout aussi
présents). Surtout que là les problèmes principaux sont dus me
semble-t-il au fait que l'on est toujours sur du Java 8 pour Scilab. Je
crois que Clément travaille sur les modifs à faire pour que nous
passions à Java 11 mais tu dois savoir que tous ceux qui sont passés
chez ESI s'occupent de Scilab en temps que tel sur leurs heures perdues.
Et moi j'essaye d'empêcher Samuel de faire perdre son temps à tout le
monde...

Mais je suis prêt à donner un coup de main si, bien sûr. Si je comprends
bien il faudrait que nous intégrions des correctifs qui ont été
nécessaires du côté Ubuntu ?

A+

Stéphane

[Simon Chopin (schopin)]

Here are debdiffs to fix this particular bug. The new approach is to backport only the patch addressing the issue at hand, rather than updating the whole package to a new version.

[Simon Chopin (schopin)]

For the Bionic fix, I might revisit it to bundle the SRU with a fix for https://bugs.launchpad.net/ubuntu/+source/scilab/+bug/1765503 as it seems a patch is available upstream.

[Simon Chopin (schopin)]

OK, I'm giving up on 1765503, the patch is non-trivial to backport and I don't know enough about the topic. Looking for sponsors now.

Hello Norbert, or anyone else affected,

Accepted scilab into focal-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/scilab/6.1.0+dfsg1-1ubuntu3.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-focal to verification-done-focal. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-focal. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.
