Hello, I've prepared an offline pack on my computer by running the following command: > `bin\logstash-plugin prepare-offline-pack --output syslog-output.zip logstash-output-syslog` When I move the zip to the server with no internet access I run the following command: > `bin\logstash-plugin install file:///D:/ELK/logstash-5.3.0/offline-packages/syslog-output.zip` I get the error: > `Could not find gem 'logstash-output-syslog (= 3.0.1) java' in any of the gem sources listed in your Gemfile or installed on this machine.` I've turned on Debug=1, full output below. It looks like there is a problem unpacking the zip file, possible a clash between unix and windows path formats? Local environment: - Windows Server 2016 - Java version 1.8.0\_121 - Logstash 5.3.0 Full debug output is here - [Local file: /D:/ELK/logstash-5.3.0/offline-packages/syslog-output.zipInstallin - Pastebin.com](https://pastebin.com/FfBmTdWs) (sorry it was too long for the post) ---

There was an issue with Logstash on 5.3.0 creating corrupted pack, Can you try with Logstash 5.3.1? ---

I'm encountering the same issue in 5.4.0, has the fix applied in 5.3.1 been carried forward to 5.4.0? ---

The fix should have been included in 5.4.0, [https://github.com/elastic/logstash/pull/6840](https://github.com/elastic/logstash/pull/6840) (merged in 5.x before we cut the release branch) @toca you are experiencing the same issue on windows? ---

OK, I can confirm that the fix was not included in 5.4.0. The bug original from paquet a gem that we are using to manage the offline dependencies. The problem is fixed with paquet 0.2.1 but LS 5.4 ships with [paquet 0.2.0](https://github.com/elastic/logstash/blob/v5.4.0/Gemfile.jruby-1.9.lock#L527) The problem is fixed in LS 5.4.1, but in the meantime, you can generate a pack with LS 5.3.1 and use it in LS 5.4.0. ---
