[Bioc-devel] Issue updating package

[...]

I have fixed it and updated it in both the release and the devel branches.
However, the build fails because a suggested package, mCSEA, is not
available.

It seems to me that the error is on Bioconductor side due to the package
"backports" which is missing in palomino3 [1]. You'll see this broken
dependency chain in Bioc 3.15 check reports: shinyepico -> mcSEA -> Gviz
-> biovizBase -> backports

I don't see anything wrong in the `backports` report [2] on CRAN.
