Looks like a dependency error.

Also, which release of Talend Studio 8 are your trying to install? May 2024?

[Rahmanadwi]

can you check the java version of each of the instance make sure they are using same java version

[bymer_mey]

It's the release of October 2022.

For the dependency, is it normal that even if i'm on ubuntu 64bit, when executing, the log talks about win32

!ENTRY org.eclipse.compare.win32 4 0 2024-10-04 11:02:10.731

v2?

Anyway, makes [EDIT] no differences for my following comment because both supports org.apache.log4j_1.2.19.TALEND.

You are running Talend Studio V8 202210 with org.apache.log4j_1.2.22.TALEND but the shipped package is org.apache.log4j_1.2.19.TALEND; see: https://update.talend.com/Studio/8/updates/R2022-10v2/plugins/org.apache.log4j_1.2.19.TALEND.jar

Have you tried to use shipped log4j version?

I'm reviewing some CVE but the suggestion is to update your Talend montly release.

[bymer_mey]

No it didn't work.

I tried to execute Talend with wine

wine Talend-x86-64.exe

 and it works without changing anything. 

So may be something is missing for the linux compatibility in the talend archive i'm using
