On macOS, you tried to install the dependencies with pip and encountered the following error:

You have not agreed to the Xcode license agreements, please run 'xcodebuild -license' (for user-level acceptance) or 'sudo xcodebuild -license' (for system-wide acceptance) from within a Terminal window to review and agree to the Xcode license agreements.

The Xcode compiler is installed but requires you to accept its license agreement prior to using it. Run xcodebuild -license to agree and then retry installing the dependencies.

You are running an old version of pip that cannot build the pycrypto dependency. Upgrade to a new version of pip by running sudo pip install -U pip.
You tried to install Algo and you see many repeated errors referencing TypeError, such as TypeError: '>=' not supported between instances of 'TypeError' and 'int' and TypeError: must be str, not bytes. For example:
TASK [Wait until SSH becomes ready...] *****************************************
An exception occurred during task execution. To see the full traceback, use -vvv. The error was: TypeError: must be str, not bytes
fatal: [localhost -> localhost]: FAILED! => {"changed": false, "failed": true, "module_stderr": "Traceback (most recent call last):\n File \"/var/folders/x_/nvr61v455qq98vp22k5r5vm40000gn/T/ansible_6sdjysth/ansible_module_wait_for.py\", line 538, in <module>\n main()\n File \"/var/folders/x_/nvr61v455qq98vp22k5r5vm40000gn/T/ansible_6sdjysth/ansible_module_wait_for.py\", line 483, in main\n data += response\nTypeError: must be str, not bytes\n", "module_stdout": "", "msg": "MODULE FAILURE"}
You may be trying to run Algo with Python3. Algo uses Ansible which has issues with Python3, although this situation is improving over time. Try running Algo with Python2 to fix this issue. Open your terminal and cd to the directory with Algo, then run: virtualenv -p `which python2.7` env && source env/bin/activate && pip install -r requirements.txt
You tried to install Algo and you see an error that reads "ansible-playbook: command not found."
You did not finish step 4 in the installation instructions, "Install Algo's remaining dependencies." Algo depends on Ansible, an automation framework, and this error indicates that you do not have Ansible installed. Ansible is installed by pip when you run python -m pip install -r requirements.txt. You must complete the installation instructions to run the Algo server deployment process.
You tried to run Algo and it quickly exits with an error about a bad owner or permissions:
fatal: [104.236.2.94]: UNREACHABLE! => {"changed": false, "msg": "Failed to connect to the host via ssh: Bad owner or permissions on /home/user/.ssh/config\r\n", "unreachable": true}
You need to reset the permissions on your .ssh directory. Run chmod 700 /home/user/.ssh and then chmod 600 /home/user/.ssh/config. You may need to repeat this for other files mentioned in the error message.
Little Snitch is not compatible with IPSEC VPNs due to a known bug in macOS and there is no solution. The Little Snitch "filter" does not get incoming packets from IPSEC VPNs and, therefore, cannot evaluate any rules over them. Their developers have filed a bug report with Apple but there has been no response. There is nothing they or Algo can do to resolve this problem on their own. You can read more about this problem in issue #134.
This issue appears intermittently due to issues with MTU size. If you experience this issue, we recommend filing an issue for assistance. Advanced users can troubleshoot the correct MTU size by retrying ping with the "don't fragment" bit set, then decreasing packet size until it works. This will determine the correct MTU size for your network, which you then need to update on your network adapter.
E.g., On Linux (client -- Ubuntu 16.04), connect to your IPsec tunnel then use the following commands to determine the correct MTU size:
$ ping -M do -s 1500 www.google.com
PING www.google.com (74.125.22.147) 1500(1528) bytes of data.
ping: local error: Message too long, mtu=1438
Then, set the MTU size on your network adapter (wlan0 or eth0):
$ sudo ifconfig wlan0 mtu 1438
You want to install Algo to a specific region in a cloud provider, but that region is not available in the list given by the installer. In that case, you should file an issue. Cloud providers add new regions on a regular basis and we don't always keep up. File an issue and give us information about what region is missing and we'll add it.
This setting is enforced on your client device via the Apple profile you put on it. You can edit the profile with new settings, then load it on your device to change the settings. You can use the Apple Configurator to edit and resave the profile. Advanced users can edit the file directly in a text editor. Use the Configuration Profile Reference for information about the file format and other available options. If you're not comfortable editing the profile, you can also simply redeploy a new Algo server with different settings to receive a new auto-generated profile.
You tried to install the Apple profile on one of your devices and you received an error stating The "VPN Service" payload could not be installed. The VPN service could not be created. Client support for Algo VPN is limited to modern operating systems, e.g. macOS 10.11+, iOS 9+. Please upgrade your operating system and try again.
In order to connect to the Algo VPN server, your router must support IKEv2, ECC certificate-based authentication, and the cipher suite we use. See the ipsec.conf files we generate in the config folder for more information. Note that we do not officially support routers as clients for Algo VPN at this time, though patches and documentation for them are welcome (for example, see open issues for Ubiquiti and pfSense).
You're trying to connect Ubuntu or Debian to the Algo server through the Network Manager GUI but it's not working. Many versions of Ubuntu and some older versions of Debian bundle a broken version of Network Manager without support for modern standards or the strongSwan server. You must upgrade to Ubuntu 17.04 or Debian 9 Stretch, each of which contain the required minimum version of Network Manager.
If you have an issue that you cannot solve with the guidance here, file an issue that describes the problem and we'll do our best to help you. You can also join our Slack and ask for help in the #algo-support channel.
