5.2.3 Failure to install Extensions...

KNIME Analytics Platform
1

When attempting to install File_Install KNIME Extensions - repeated failure with below unreachable resources - cannot reach any of the target servers/content. Regardless of network or DNS, nothing is returning.
I do not believe it is a DNS/Routing issue on my side, it acts like the repository is offline. Please advise.
Thank you

Some sites could not be found. See the error log for more detail.

Dear @nickbissett,

which extension are you trying to install? Does it also happen with KNIME internal extensions, e.g. KNIME Textprocessing – KNIME Community Hub ?

I am trying to utilize “Data Explorer” by going to File_Install KNIME Extensions

when doing that i fail with the stated errors…I have done this via wired ETH conn, Wireless ETH connections across 3 different sites.

Unless it is a security policy on my laptop - i am confident it isn’t network.

Dear @nickbissett,

I am sorry for the trouble. Some more questions to hopefully nail it down:

  1. Did this issue occur before when installing extensions? If yes, did anything change? Or is it the first time you install extensions?
  2. And you are saying that even when trying to install the extension from outside of your corporate network, the install process results in the same error?
  3. I asked and the best guess we have is that somewhere between your machine and our server there is an obstacle - if you can rule out proxy issues (if you confirm the point above), then maybe a firewall issue? Did you try it with another laptop with a different setting, e.g. different OS?

Best regards
Steffen

Great Questions and the short answer is:

  1. This is my first install. I have not installed on another laptop
  2. Yes. Failure across multiple networks with various security postures.
  3. I am not clear if there some type of ‘black list’ issue or proxy issue or local Firewall on my laptop that could be causing this - i have opened a case with my IT Support team to investigate and advise

Any additional thoughts i can peruse given this information?

Thank you for your support.

@nickbissett have you tried an ‘offline’ installation of extensions from a local (zip) repository?

If you are trying to install Python based extensions on a machine behind a firewall there might be additional steps necessary:

Dear @nickbissett,

  1. Ok: we have a laptop which could never reach the update sites
  2. On that laptop the install process has been attempted from different networks, also ones without proxy and additional security measures (correct?) - without success
  3. We do not know whether the laptop itself has some more rigorous security setup and
  4. we do not know yet whether the install process would work with another machine, because it has not been attempted yet.
  5. A workaround could be downloading the update sites and use them offline

The fifth point should circumvent the issue, but I am still curious about the other points. If you find time to further pursue them, I would be interested in their results.

Tell me whether 5. works for you.

Best regards
Steffen

PS: just saw that @mlauber71 send the fifth point as well.
