Ingest-attachment not found

Elastic Stack Elasticsearch
1

Hi,

I'm trying to install the ingest-attachment (using elasticsearch-plugin install ingest-attachment). I'm behind a proxy, so I use this line:

sudo CLI_JAVA_OPTS="-Dhttp.proxyHost=192.168.0.1 -Dhttp.proxyPort=8080 -Dhttps.proxyHost=192.168.0.1 -Dhttps.proxyPort=8080" ./elasticsearch-plugin install ingest-attachment

But this doesn't work (Exception in thread "main" java.net.ConnectException: Connection timed out). So I added --verbose, which shows me the attempt to download this file:
https://artifacts.elastic.co/downloads/elasticsearch-plugins/ingest-attachment/ingest-attachment-linux-x86_64-7.10.2.zip

Checking this address in my browser or via wget shows: this file doesn't seem to exist.

Ho can I install ingest-attachment on Ubuntu 20.04.5 LTS anyway?

Best regards,

Please upgrade your Elasticsearch version. At least to 7.17.8 but better to 8.5.3.

Sorry, my bad. I did an upgrade. Now it tries to download this file here:
https://artifacts.elastic.co/downloads/elasticsearch-plugins/ingest-attachment/ingest-attachment-linux-x86_64-7.17.8.zip
If I try to download this file via browser, nothing happens. A download via wget also fails.

Interesting.

Try something like:

sudo CLI_JAVA_OPTS="-Dhttp.proxyHost=192.168.0.1 -Dhttp.proxyPort=8080 -Dhttps.proxyHost=192.168.0.1 -Dhttps.proxyPort=8080" ./elasticsearch-plugin install https://artifacts.elastic.co/downloads/elasticsearch-plugins/ingest-attachment/ingest-attachment-7.17.8.zip

Does this work?

Thank you. Halfway there. Still an error:

-> Failed installing https://artifacts.elastic.co/downloads/elasticsearch-plugins/ingest-attachment/ingest-attachment-7.17.8.zip
Exception in thread "main" java.net.ConnectException: Connection timed out

But If I enter the address provided in my browser or use it with wget, the file gets downloaded. So the address is correct.

Here is the whole error-message:

Since the download via wget works: can I somehow install it manually?
Like so:

cd ~
wget https://artifacts.elastic.co/downloads/elasticsearch-plugins/ingest-attachment/ingest-attachment-7.17.8.zip
cd /usr/share/elasticsearch/bin
sudo ./elasticsearch-plugin install ~/ingest-attachment-7.17.8.zip

This doesn't work yet:

sudo ./elasticsearch-plugin install ~/ingest-attachment-7.17.8.zip

I tried to cheat and uploaded the zip-file on an internal webserver. After that, I ran:

sudo ./elasticsearch-plugin install https://mywordpressserver/wp-content/uploads/2022/12/ingest-attachment-7.17.8.zip

But it gave me:

Exception in thread "main" java.net.UnknownHostException: mywordpressserver

Another attempt with ip-address (sudo ./elasticsearch-plugin install https://192.168.100.1/wp-content/uploads/2022/12/ingest-attachment-7.17.8.zip) comes to:

Exception in thread "main" javax.net.ssl.SSLHandshakeException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

I have a valid domain-certificate with san-attributes (which means the ip-address is included), but I guess I would have to introduce my certificate authorities to the local java instance.

And actually I wouldn't want to cheat like this but install it in a proper way. Downloading via wget and installing it manually would still be acceptable though.

Figured it out (using a pre-downloaded file):

cd ~
wget https://artifacts.elastic.co/downloads/elasticsearch-plugins/ingest-attachment/ingest-attachment-7.17.8.zip
cd /usr/share/elasticsearch/bin
sudo ./elasticsearch-plugin install file:///home/myusername/ingest-attachment-7.17.8.zip
sudo systemctl restart elasticsearch

Works now.
Syntax for using local files during an installation is file:///path/to/file, not just the path/filename.

Best Regards,

PS: still no idea, why the setup wouldn't use my proxy...
