License activation issue

I'm currently trying to setup a CI pipeline. I'm already stuck at the license activation. I already found out that the .alf file needs to be created on the CI machine itself and not on an other machine. I now successfully created an .ulf file and added it to the environment vars, it's content is successfully written to /root/.local/share/unity3d/Unity/Unity_lic.ulf (verified).

When running the build script I get following output (played around with -nographics here, but makes no difference):

/opt/Unity/Editor/Unity -nographics -batchmode -manualLicenseFile "$LICENSE_FILE" -logfile
CreateDirectory '/root/.cache/unity3d' failed:  (current dir: /builds/ams-isd/big-tomato-ar-app)

 Load manual activation license file.

I also tried to activate the license by passing -password and -username after deleting /root/.local/share/unity3d/Unity/Unity_lic.ulf but received an timeout during activation as mentioned in #43 (CI and local).

I'm using a Unity Personal license and the gableroux/unity3d:2018.2.6f1 image.

I'm aware that this is not a problem with this project but most likely with Unity itself bu I hope somebody here came across this before! Nothing useful is on the web about this...
