Download old version of GeoGebra 5 (Linux/deb)
unfortunately an update broke my file (is attached, can it be fixed in a future version or did I use an feature that was removed?), it worked at the beginning of February, but not anymore. The oldest version I could find on the server is 5.0.524 (build 667890). I need 5.0.523 or older, there are 3rd-party sites that hosts old windows versions, and with 5.0.523 it works (it was also last modified with that version).
