Mint is based on Ubuntu. But here is the solution.
make a copy of your file: /etc/os-release which is probably a link to /usr/lib/os-release
Then edit the file like this:
--- /usr/lib/os-release 2018-02-12 19:21:45.000000000 +0100
+++ /usr/lib/os-release.sdkmanager 2021-11-15 10:47:37.818237598 +0100
