Package installation task shows failed

As per details shared by the development team, the new application release has some dependencies on the back end. There are some packages/services that need to be installed on all app servers under Stratos Datacenter . As per requirements please perform the following steps:

a. Install {{ WEBPKG }} package on all the application servers.

b. Once installed, make sure it is enabled to start during boot.

Since no package mentioned, i went through the forum and installed the squid package. Tried to validate and it shows tasks failed. I have raised a review and directed to post in the community forum.
Please reset my task, so that I can finish that
