Mono: cert-sync missing?

[ConradHughes]

For new Package Requests, see the guidelines

Setup

Package Name: Mono
Package Version: 3.10.0 (mono -V)

NAS Model: Synology DS713+
NAS Architecture: Atom D2700
DSM version: 6.1.4-15217 Update 2

Expected behavior

I'm trying to run Duplicati 2.0.2.13 using this version of Mono. I'd hope it would run without complaint.

Actual behavior

As Duplicati starts up I get this warning/error:

No certificates found, you can install some with one of these commands:
    cert-sync /etc/ssl/certs/ca-certificates.crt #for Debian based systems
    cert-sync /etc/pki/tls/certs/ca-bundle.crt #for RedHat derivatives
Read more: http://www.mono-project.com/docs/about-mono/releases/3.12.0/#cert-sync

.. I can find various resources commenting on this, but they all expect cert-sync to be available. I've run "find / -name cert-sync", and it is not present. There were various comments a year or two ago in the "DSM 6.0 experiences" thread which suggest other people are missing cert-sync and expect it to be run during Mono post-install; did anything come of this?

Steps to reproduce

1. Install Mono from SynoCommunity.
2. Install Duplicati from their .spk.
3. Run /volume1/\@appstore/mono/bin/mono /volume1/\@appstore/Duplicati/Duplicati.Server.exe --webservice-interface=any --webservice-port=8200

ssh into your box and execute the following command:

/var/packages/mono/target/bin/cert-sync /etc/ssl/certs/ca-certificates.crt

An update fixing this issue (and others) is coming, but pending publication.

Edit: Sorry, should have read your full post. OK, you will need a newer mono version. Just manually upgrade to a pre-publication package from here then.

@m4tt075 My attempt to build latest mono (already merged) with arch-x64-5.2 fails with many issues. Here is first of them:

I compile with Docker image. Is there any additional requirements to succeed ?

[m4tt075]

@ymartin59 Hmh, the same package just compiled fine in my VirtualBox environment. If you have built other (possibly 6.1) packages before, you should run make clean in the native/mono directory in addition to the spk/mono directory. This is not automatic and might be the culprit. Otherwise, no idea...

[ConradHughes]

Thanks for such a quick and helpful response @m4tt075 — as you suggested, the latest pre-publication version that you pointed me at (Mono 6.1_5.4.1.6-9) solves the cert issue, and that (it turns out) solves other problems that I thought were unconnected.

Is there a problem with the release process that the officially available SynoCommunity version (3.1) is so far behind?

[m4tt075]

@ConradHughes Happy to hear that. We have had some significant challenges with Synology's changes to third party packages, some of which still need to be finally addressed. And we do not have a lot of developers, so everything just takes a volunteer willing and interested to look into certain packages or problems and (usually some more) time. Open source stuff. Needs to stay fun. That's all.

@m4tt075 There is chance mono compilation uses tools available in your ubuntu virtual box... but no available in Debian Docker image...
@Safihre May you help about this mono compilation issue (see few comments below) ? How did you build your packages ?

[Safihre]

@ymartin59 I use also the Docker image via Travis, it very simply does:

docker pull synocommunity/spksrc; 
docker run -it -v `pwd`:/spksrc synocommunity/spksrc /bin/bash -c "cd /spksrc && make setup && cd spk/$PKG && make $SYNOARCH >/dev/null"

https://travis-ci.org/Safihre/spksrc/builds/309734708

[ymartin59]

@m4tt075 @Safihre I wonder if compilation succeeds for you because of compilation has been done before with previous version. Is it really expected cross/mono/Makefile PKG_VERS_MAJOR is still 4.6.2 ?!?

[Safihre]

Huh? It says 5.4.1?
https://github.com/SynoCommunity/spksrc/blob/master/cross/mono/Makefile#L2
My Travis pulls a fresh Docker image every time, no caches or anything.

[Safihre]

Ahh, I see that in the dsm6 branch it's still 4.6.1.
For my Travis builds I manually applied the PR of @m4tt075 to the dsm6 branch.

We really need to go to 1 branch and not master/dsm6! 💯

[ymartin59]

Stupid me, I was on dsm6 branch... I let it for later, I am working on service user creation...

[m4tt075]

@ymartin59 Just for you, Sir! PR #3039 😃

[Safihre]

Should now all be fixed with the new mono release that also preserves certificates correctly on DSM update.
