Install SynxDB CE

1. Download the public key

Fetch the armored key from https://www.synxdata.com/keys/synxdb-ce.asc, then confirm its fingerprint matches what your signup email shows. The fingerprint is the trust anchor, if the value gpg --show-keys reports differs from the email, do not import the key.

# Download the SynxDB CE public signing key
curl -O https://www.synxdata.com/keys/synxdb-ce.asc

# Confirm the fingerprint matches what's in your signup email
gpg --show-keys synxdb-ce.asc | awk '/^ /{print; exit}'
# Expected: A965 E32F 0312 ECAF EC26  831E 72B2 635D 204E 5473

On a minimal Rocky 9 install, gpg is provided by the gnupg2 package: sudo dnf install -y gnupg2.

2a. Verify on Rocky Linux 9 / RHEL 9 (RPM)

Import the key into the system's RPM keyring, then ask rpm to check the package signature.

# Install the key into the system RPM keyring
sudo install -m 644 synxdb-ce.asc /etc/pki/rpm-gpg/RPM-GPG-KEY-synx-community
sudo rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-synx-community

# Confirm the key landed in the keyring
rpm -q gpg-pubkey --qf '%{summary}\n' | grep -i synx
# Expected: Cloudsmith Package (synx/community) <support@cloudsmith.io> public key

# Verify the package signature
rpm --checksig synxdb-ce-*.rpm
# Expected: synxdb-ce-...rpm: digests signatures OK

2b. Verify on Ubuntu 22.04 LTS (DEB)

Import the key into a dedicated keyring, then verify the .deb with dpkg-sig.

# Install the verifier (one-time)
sudo apt-get update
sudo apt-get install -y dpkg-sig gnupg

# Import the key into a dedicated keyring
sudo gpg --no-default-keyring --keyring /usr/share/keyrings/synx-community.gpg \
  --import synxdb-ce.asc

# Confirm the fingerprint matches
gpg --no-default-keyring --keyring /usr/share/keyrings/synx-community.gpg \
  --list-keys --fingerprint
# Expected fingerprint: A965 E32F 0312 ECAF EC26  831E 72B2 635D 204E 5473

# Verify the package signature
dpkg-sig --verify synxdb-ce_*.deb
# Expected: GOODSIG _gpgbuilder 72B2635D204E5473 ...

3a. Install on Rocky Linux 9 / RHEL 9

SynxDB CE depends on a handful of packages that ship through EPEL (xerces-c) and the CodeReady Linux Builder repo (perl-IPC-Run). Both are part of the Rocky / RHEL ecosystem but are not enabled by default on a fresh install, enable them once, then dnf install resolves everything from there.

# Enable EPEL (for xerces-c) and CRB (for perl-IPC-Run)
sudo dnf install -y epel-release dnf-plugins-core
sudo dnf config-manager --set-enabled crb

# Install the verified RPM
sudo dnf install -y ./synxdb-ce-*.rpm

# Confirm
rpm -qi synxdb-ce

On RHEL 9 the equivalent of CRB is named codeready-builder-for-rhel-9-x86_64-rpms, enable with subscription-manager repos --enable instead of dnf config-manager.

3b. Install on Ubuntu 22.04 LTS

All runtime dependencies resolve from the default main and universe repositories that ship with Ubuntu 22.04, no extra repos to enable.

# Install the verified DEB (apt resolves runtime deps from main + universe)
sudo apt-get update
sudo apt-get install -y ./synxdb-ce_*.deb

# Confirm
dpkg -s synxdb-ce | head
