**WARNING**
Invalid alternates have been detected.
Beginning with version 2.0.0, yadm uses a new naming convention for alternate
files. Read more about this change here:
https://yadm.io/docs/upgrade_from_1
Or to learn more about alternates in general, read:
https://yadm.io/docs/alternates
To rename the invalid alternates run:
yadm mv <old name> <new name>
