-Next troubleshooting command sequence for dpkg corruption:
-
-```bash
-sudo cp /var/lib/dpkg/info/node-lodash-packages.list /var/lib/dpkg/info/node-lodash-packages.list.bak 2>/dev/null || true
-printf '\n' | sudo tee -a /var/lib/dpkg/info/node-lodash-packages.list >/dev/null
-sudo dpkg --configure -a

-sudo apt autoremove -y
-sudo apt clean
-sudo apt update
-sudo apt install -y nodejs npm
-node -v
-npm -v

-
-If that fails, move the corrupted dpkg info files aside and retry:
-
-```bash
-sudo mkdir -p /root/dpkg-node-lodash-packages-backup
-sudo mv /var/lib/dpkg/info/node-lodash-packages.* /root/dpkg-node-lodash-packages-backup/ 2>/dev/null || true
-sudo dpkg --configure -a
-sudo apt --fix-broken install
-sudo apt purge -y nodejs npm libnode* node-* || true
-sudo apt autoremove -y
-sudo apt clean
-sudo apt update
-sudo apt install -y nodejs npm

-If `node -v` still segfaults after clean apt install, strongly consider switching Raspberry Pi to Raspberry Pi OS Lite 64-bit or using backend runtime alternatives.
+- For `arm64` and `amd64`, it can use NodeSource.
