Nextcloud on Ubuntu 24.04 LTS

Nextcloud is the leading self-hosted content-collaboration platform: file sync and share, calendars, contacts, and office editing. This image gives you a production-ready deployment within minutes of first boot — no dependency wrangling, no manual hardening checklist. Published and maintained by Derek Coleman & Associates Inc: freshly rebuilt against current security advisories and deployable straight from the Azure Marketplace into your own subscription.

Nextcloud 30 installed from the official upstream source

Trusted Launch support: Secure Boot + vTPM
Azure Monitor Agent, Defender for Cloud, and Update Manager install cleanly

Quick start

Known issue on the current image (as of 2026-09-15) — First boot aborts before Nextcloud is installed: no admin account and no /var/lib/nextcloud-firstboot-admin-pw are ever created, and http://<VM-IP>/ never shows the Nextcloud login. Workaround and fix status on the support page.

Deploy from the Azure Marketplace (Get It Now → Create), choosing your SSH key at the Administration step.
Allow inbound SSH (22) for yourself plus the application port(s): 80 and 443 (web UI) — restrict to your own IP where possible. The in-image firewall already allows them; only the Network Security Group (NSG) keeps them closed.
Wait for first boot to finish, open http://<VM-IP>/ and sign in as admin (see First login below).
Point a DNS name at the VM, run `sudo certbot --apache -d your.domain`, and add the domain to trusted_domains.

Get your admin password (one time)

ssh <your-username>@<VM-IP>
sudo cat /var/lib/nextcloud-firstboot-admin-pw

Every image ships without any shared or default password — a unique admin credential is generated for your VM on first boot. Change it after first sign-in.

Common use cases

Private file sync and share
Team document collaboration
Calendar, contacts, and mail in one place
GDPR-friendly alternative to public clouds
