Debian Support

steps to reproduce:

0. reqs export URL=$your_pulp_fqdn export REPO_NAME=buster-releases wget http://ftp.de.debian.org/debian/pool/main/j/jq/jq_1.5+dfsg-2+b1_amd64.deb wget http://ftp.de.debian.org/debian/pool/main/j/jq/jq_1.6-1_amd64.deb

1. create repo export REPO=$(http ${URL}/pulp/api/v3/repositories/deb/apt/ name=${REPO_NAME} | jq -r '.pulp_href')

2. create content from file http --form POST ${URL}/pulp/api/v3/content/deb/packages/ file@jq_1.5+dfsg-2+b1_amd64.deb repository=${REPO}

3. create publication http POST ${URL}/pulp/api/v3/publications/deb/apt/ repository=${REPO} simple=true export PUB=$pulp_href_from_task_above

4. host publication (create distribution) http POST ${URL}/pulp/api/v3/distributions/deb/apt/ name=${REPO_NAME} base_path=${REPO_NAME} publication=${PUB} export DISTR=$pulp_href_from_task_above

5. add same package different version http --form POST ${URL}/pulp/api/v3/content/deb/packages/ file@jq_1.6-1_amd64.deb repository=${REPO}

6. add publication from latest $REPO http POST ${URL}/pulp/api/v3/publications/deb/apt/ repository=${REPO} simple=true export PUB=$pulp_href_from_task_above

http PUT ${URL}${DISTR} name=${REPO_NAME} base_path=${REPO_NAME} publication=${PUB}

Expected result: both .debs are stored under single directory in ${URL}/pulp/content/buster-releases/pool/all/j/jq, similar to what official debian repos do, i.e: http://ftp.de.debian.org/debian/pool/main/j/jq/

Actual Result: package with same name stored in different paths. i.e: jq (1.5+dfsg-2)/ jq/

Additionally, when trying to download .deb for "jq (1.5+dfsg-2)", pulp throws 500 with following exception:
