While this comes too late for signing the tag of your submitted thesis
(congratulations!), this is likely caused by a missing GPG_TTY variable.

https://www.gnupg.org/documentation/manuals/gnupg/Common-Problems.html

The gpg-agent man page nowadays includes the following hint:

  It is important to set the GPG_TTY environment variable in your login
  shell, for example in the ‘~/.bashrc’ init script:

  export GPG_TTY=$(tty)
