Installing AcelleMail on Ubuntu 22.04 LTS

What this is for#

Ubuntu 22.04 LTS ("Jammy Jellyfish") is supported through April 2027 and remains a perfectly fine host for AcelleMail in 2026. The install flow is nearly identical to Ubuntu 24.04 — same Ondrej PHP PPA, same MySQL 8.0, same nginx + certbot + supervisor stack. This article documents only the differences. For the full step-by-step, follow the canonical guide.

👉 Canonical guide: Install AcelleMail on Ubuntu 24.04 LTS

Every step in that guide works on Ubuntu 22.04 unchanged, except for the small differences below.

Difference 1 — PHP comes from the Ondrej PPA, not universe#

Ubuntu 22.04's universe ships PHP 8.1, which is below AcelleMail's minimum (PHP 8.3). On 24.04 you can ostensibly use universe's PHP 8.3 directly; on 22.04 you must use the Ondrej PPA. The commands in Step 2 of the canonical guide already install via Ondrej, so no change is needed:

sudo add-apt-repository -y ppa:ondrej/php
sudo apt-get update -y
sudo apt-get install -y php8.3 php8.3-fpm php8.3-mysql php8.3-mbstring \
    php8.3-xml php8.3-curl php8.3-zip php8.3-gd php8.3-intl \
    php8.3-imap php8.3-gmp php8.3-sqlite3 php8.3-mailparse php8.3-bcmath \
    php8.3-redis

Verify Ondrej is the active source before installing — ondrej/php should appear in apt-cache policy php8.3. If you see Ubuntu's universe listed instead, the PPA wasn't added; re-run the add-apt-repository command.

Difference 2 — MySQL 8.0 from universe (same as 24.04)#

Both 22.04 and 24.04 ship MySQL 8.0 in universe. Step 3 of the canonical guide works without changes.

Difference 3 — Nginx 1.18 vs 1.24#

Ubuntu 22.04's universe ships nginx 1.18; 24.04 ships 1.24. Both work fine with AcelleMail's vhost — there are no AcelleMail-specific nginx 1.24+ features. The vhost from Step 5 of the canonical guide is identical.

If you want nginx 1.24+ on Ubuntu 22.04 (for HTTP/3 or other newer features), add the official nginx.org PPA:

sudo add-apt-repository -y ppa:ondrej/nginx
sudo apt-get update -y
sudo apt-get install -y nginx

For most AcelleMail installs this is unnecessary — nginx 1.18 is stable and well-tested.

Difference 4 — Support window#

If you're provisioning a new server today and have a free choice, prefer 24.04. If you're already on 22.04 with a working install, no urgency to upgrade — both are LTS and both receive security updates.

All other steps — follow the canonical 24.04 guide#

For:

• Step 0 (pre-flight checklist)
• Step 1 (system packages)
• Step 3 (MySQL 8.0 setup with utf8mb4)
• Step 4 (Redis 7)
• Step 5 (nginx vhost — paste verbatim)
• Step 6 (drop in the bundle)
• Step 7 (TLS with certbot)
• Step 8 (supervisor for queue worker)
• Step 9 (cron)
• Step 10 (web installer — with all 3 wizard screenshots)
• Post-install verification + Common Issues table

→ Use Install AcelleMail on Ubuntu 24.04 LTS verbatim.

When to choose 22.04 over 24.04#

• You're standardising on Ubuntu 22 across your infrastructure and don't want OS-version sprawl
• You already have other 22.04 servers with battle-tested operational tooling
• Your hosting provider's 22.04 images are more polished than their 24.04 images (some cheaper VPS providers shipped buggy 24.04 images in 2024)

In any other scenario, prefer 24.04 — you get an extra 2 years of LTS support for free.

Common issues specific to 22.04#

For all other failure modes, see the Common Issues table in the canonical 24.04 guide.
