Azure Knime Server - install extenstion failed

Hello,

I’'m trying to install additional extension to Knime Server Small (Azure) with following command:
./knime -application org.eclipse.equinox.p2.director -nosplash -consolelog -r https://update.knime.com/community-contributions/4.5 -i org.anotherfraud.excel.feature.feature.group -d opt/knime/knime-4.5.1

I’ve founded it there: KNIME Server Administration Guide

Unfortunately, I’m receiving this error:
Unable to init server: Could not connect: Connection refused
Knime: Cannot open display:
Knime:
The Knime executable launcher was unable to locate its
companion shared library

I will appreciate any suggestion.

Thanks in advance!

Hello @Elderion,

The command is almost right, there is only the first slash missing in the path of the -d option, so this should work:

./knime -application org.eclipse.equinox.p2.director -nosplash -consolelog -r https://update.knime.com/community-contributions/4.5 -i org.anotherfraud.excel.feature.feature.group -d /opt/knime/knime-4.5.1

Best,
Michael

Hi @MichaelRespondek

thank you for your answer. I’ve checked it - didn’t help. It looks like, the problem is related to permission. I can install the extension only after changing folder permissions:

sudo chmod -R 777 knime-executor
sudo chmod -R 777 knime-4.5.1

After it, I can, for example, install nodepit:

sudo ./knime -application org.eclipse.equinox.p2.director -nosplash -consolelog -r https://download.nodepit.com/nodepit/4.5 -i com.nodepit.knime.feature.feature.group -d /opt/knime/knime-4.5.1

But, I can’t still install AF Utility Nodes. :frowning: I’m using this command:
sudo ./knime -application org.eclipse.equinox.p2.director -nosplash -consolelog -r https://update.knime.com/community-contributions/4.5 -i org.anotherfraud.excel.feature.feature.group -d /opt/knime/knime-4.5.1

Hi @Elderion,
In your screenshot is a missing eclipse dependency logged. Therefore you have to add our main update site into the list of your sources:

sudo ./knime -application org.eclipse.equinox.p2.director -nosplash -consolelog -r https://update.knime.com/community-contributions/4.5,https://update.knime.com/analytics-platform/4.5 -i org.anotherfraud.excel.feature.feature.group -d /opt/knime/knime-4.5.1

should work for you.

Best,
Michael
