What extension(s) are you trying to install? Have you tried the Install Extensions function from the Menu?

Hi @KNIME_JK, welcome to the KNIME forum.

It looks like you are on a corporate network and your company has a proxy server that is blocking access to the KNIME update site. Are you able to contact your network administrators to ask them if access can be granted?

Proxy Authentication Required

Hello YGD, Having the same issue. The only way that I got to know is either to switch off the proxy/ VPN for some time or you can ask the IT team to allow “hub.knime.com” and “update.knime.com” with the proxy. Really a problem as I can’t even update KNIME version

The alternative, if you are able to get access to the update files by other means is to download the update files and then perform an offline update.

Install extensions and updates offline

Hello @lsandinop , here is our documentation where you can find how to download KNIME update sites as zip files: https://docs.knime.com/latest/analytics_platform_installation_guide/index.html#_adding_local_update_sites Regards, Dora

Better though if you can persuade somebody to allow access!

Hey all,

thanks guys. I have now deactived the proxy

After the installation assistant was finfished, it tried to install, after 16% and 15 min. an other error shows up:

An error occurred while installing the items
session context was:(profile=KNIMEProfile, phase=org.eclipse.equinox.internal.p2.engine.phases.Install, operand=null → [R]com.pharmacelera.pharmacelera_extensions.channel.bin.win32.x86_64 1.1.0.202412030803, action=org.knime.product.p2.actions.ShellExec).
ShellExec command exited non-zero exit value:

To tell the whole story, bevor I have cut out the proxy, I have isntalled a part of the extansion package offline.

I am lost

cheers
