As README of logrus said, github.com/Sirupsen/logrus is the old path, anything using it should be updated to import and require github.com/sirupsen/logrus.
Some environments experienced problems with the upper-case variant, so the lower-case was decided. Everything using logrus will need to use the lower-case: github.com/sirupsen/logrus. Any package that isn't, should be changed.
Background

.Solution
Replace all the import paths, change
"github.com/Sirupsen/logrus"
to"github.com/sirupsen/logrus"
. Where did you import it: https://github.com/kacalayar/subs/search?q=github.com%2FSirupsen%2Flogrus&unscoped_q=github.com%2FSirupsen%2Flogrus
