Release blocked: 'Install xmllint' apt-get update hangs for hours in CLI Deploy

Problem

Every release attempt on 2026-08-19 stalled in Deployment / deployment → CLI Deploy → Install xmllint. The step runs:

sudo apt-get update && sudo apt-get install -y libxml2-utils

azure.archive.ubuntu.com was unreachable from the runner (every index line Ign:), apt fell back to archive.ubuntu.com, fetched the four InRelease files, then stalled forever on the Packages indices. Composite-action steps cannot carry timeout-minutes, so nothing bounded it — the job simply hung until a human cancelled.

Observed:

This is unrelated to the dev-image pgvector fix in #36807 — run -01 hung here at 15:41Z, over four hours before that PR merged (20:05Z). Run -02 failed earlier, in the dev-image build, which #36807 fixed; -03 then got past the dev image and surfaced this pre-existing hang.

Fix

xmllint is called exactly once in deploy-jfrog/action.yml, to read distributionManagement/<repository|snapshotRepository>/url out of pom.xml. Three sibling steps in the same action already read POM values with mvn help:evaluate. Use that here too and delete the apt step — the release path stops depending on Ubuntu package mirrors entirely.

Verified against pom.xml — identical output:

• repository → https://repo.dotcms.com/artifactory/libs-release-local
• snapshotRepository → https://repo.dotcms.com/artifactory/libs-snapshot-local

Start in deploy-jfrog/action.yml and compare the xmllint step with the three sibling steps that use mvn help:evaluate. Verify the deployment action no longer depends on apt package mirrors and that it produces the repository and snapshotRepository URLs shown in the issue.
