This one liner from github *should* work to install IncrediblePBX 2026 on Debian 13. Warning I haven't' tested it yet. If you test it and it doesn't work please post back.
Note, I updated it to download all its tarball dependencies from github instead of from filedn and incrediblepbx dot com, so these resources can be located in one place for people to see.
Also, I fixed it to verify it's running as root and on debian 13 before proceeding to bomb its way thru the script and execute commands without root privileges on the wrong OS.
Code:
curl -sSL https://raw.githubusercontent.com/EspaceNetworks/IncrediblePBX/main/IncrediblePBX2026.sh | sudo bash /dev/stdin
Edited: One liner.
Two lines is more reliable since it's a long running installer, if the network drops, the one liner bombs.
Code:
wget https://raw.githubusercontent.com/EspaceNetworks/IncrediblePBX/main/IncrediblePBX2026.sh
sudo bash IncrediblePBX2026.sh
