Talend Open Studio v. 7.1.1 cannot download additional packages

[Anonymous]

Hi,

I have downloaded and installed TOS-DI v7.1.1 and I am unable to install the additional packages required for ETL development and job build.

I have read on a few threads about downloading the certificate and installing it.

The machine where this version of Talend is installed does have a proxy setting which is causing this issue.

However I don't have admin access on the machine, so I asked the admin to execute the following command:

C:\Program Files\Java\jdk1.8.0_71\>.\bin\keytool -keystore .\jre\lib\security\cac erts -importcert -alias aliasforca -file %TALEND_HOME%\cer\cacert.cer

Where cacert.cer is the certificate file I downloaded from Talend website through Chrome browser.

However that has not resolved the issue. When I click on Help > Install Additional Packages, I see the Additional Talend Packages window but it still appears empty. Also the .log file present in %TALEND_HOME%\workspace\.metadata folder has the following exception logged:

Can anyone tell me what else I need to do to overcome this issue?

Hello,

Have you tried to open talend.com in browser(IE, e.g), click on cert info and export the cert files? To see if the cert info for talend.com and the Nexus site (https://talend-update.talend.com/nexus) with the jar files has been approved/signed by our certificate authority according to Internet Explorer?

Best regards

Sabrina

The certificate I have downloaded is from talend.com. But I did it from Chrome and I exported it in Base-64 format.

I am not able to understand how I can get the certificate from Internet Explorer.
