Description

I was installing an HDP 2.6.3 stack with Ambari 2.6.0.0 on Ubuntu14 and hit the following error in package installation:

"No package found for hadooplzo-${stack_version}(hadooplzo-(
d|-)+$) because the available packages list is an empty array."

In apt.py a string comparison is made on the repo ID vs information returned by apt-cache dump:

if repo_id in package[2]:

In my case the package info contained a URL encoded '_' as %5F but this was not in the repo ID:

repo_id=example_mirror_hdp_HDP_ubuntu14_2.6.3.0-235
package[2]=example_mirror%5fhdp_HDP_ubuntu14_2.6.3.0-235_dists_HDP_main_binary-amd64_Packages

I was able to work around this by editing /usr/lib/ambari-agent/lib/resource_management/core/providers/package/apt.py to URL decode the strings before comparison.
