Install hangs indefinitely

[KnorpelSenf]

The install script uses some heuristics to determine if it is run interactively or not. This setup is broken and has some false positives, i.e. it determines that it runs interactively while in fact it does not. As a result, the install script hangs indefinetely.

There also isn't a flag to force skip the interactive shell setup, so there is no known workaround atm. Existing env vars like DEBIAN_FRONTEND=noninteractive are not considered, either.

Some ways to break this are

• by breaking the -t 0 check, such as if you run the script remotely, see this
• by running the install script via kaniko during a docker build
