I have been using tximeta to get the annotation data for my RNAseq data, created by salmon. I was previously able to get the annotations for the mouse genome it was using and it had successfully downloaded the Ensembl data needed for DESeq2. But I recently deleted the .cache data for the annotaitonhub, but it now no longer is able to load the annotaiton data and produces the error shown below.

It seems resource "AH73905" is incomplete? It seems to "know" it, since it downloads some of the annotationhub data, but fails after that.

library(tximeta)
library(BiocFileCache)
library(DESeq2)
bfc <- BiocFileCache(ask = FALSE)
cache <- slot(bfc, "cache")
setTximetaBFC(cache)
r_design_matrix <- read.csv("/home/tdeboer/CODE/rnayx/rnayx/design_matrix.csv")
r_design_matrix[] <- lapply(r_design_matrix, factor)
se_full <- tximeta(r_design_matrix, useHub = TRUE)

And that produces this output.

This should be resolved now. The hubs were down unexpectedly yesterday. I'm sorry I didn't post an announcement here but will if it happens in the future. https://stat.ethz.ch/pipermail/bioc-devel/2023-October/019953.html .
