Curl error while publishing into dataverse

[wheintz]

Hi Emmanuel,
I did some other test publishing into data.inrae.fr from the rstudio server Gedeop. I thought it came from my colleague's configuration but it's more about mine! Indeed, we did a test with another colleague's account and he got the same error :

1  atom4R      TRUE     0.1
[atom4R][WARN] SwordDataverseClient - Token is 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'
[atom4R][INFO] SwordDataverseClient - GET - Sword Dataverse service document at 'https://data.inrae.fr/dvn/api/data-deposit/v1.1/swordv2/service-document'
Error in curl::curl_fetch_memory(url, handle = handle) :
  error:141A318A:SSL routines:tls_process_ske_dhe:dh key too small
In addition: Warning messages:

2: In default_backend_auto() :

3: In default_backend_auto() :

[atom4R][ERROR] SwordDataverseClient - Error while retrieving SWORD service document
 
Error in super$initialize(url = sword_api_url, version = "2", token = token,  :
  Error while retrieving SWORD service document

On my rstudio session, I don't get this error, whatever the token used. So it seems that I'm the only one able to publish ...

Thanks for your help!

Hi again,
Hi cleaned my user library, updated the system library on my server, and nothing works for me now!
Same error...

Maybe a missing library ?

You can try with your account (using system library only) on gedeop rstudio server.

Thanks!

I've tested it on my local Rstudio and on the D4Science e-infra Rstudio it works well. This issue let indicates an issue with the curl config on your Rstudio server:

error:141A318A:SSL routines:tls_process_ske_dhe:dh key too small

Looking at most of threads, it indicates the need to decrease SSL security level: See eg https://askubuntu.com/questions/1233186/ubuntu-20-04-how-to-set-lower-ssl-security-level

Hello Emmanuel,

Many thanks, it works for me!

sudo nano /etc/ssl/openssl.cnf

Add this line at the top:
openssl_conf = openssl_init

And add these lines at the end:

[openssl_init]
ssl_conf = ssl_sect

[ssl_sect]
system_default = system_default_sect

[system_default_sect]
CipherString = DEFAULT@SECLEVEL=1

Cheers,

Wilfried
