Some registries failed to update!?

When performing the command (@v1.7) pkg>up, I receive the following alert:

Error: Some registries failed to update:

from the following list:

the rest without success. I live in all this alert (summarized)

 using Images

ERROR: LoadError: InitError: Artifact "OpenSpecFun" was not installed correctly. Try `using Pkg; Pkg.instantiate()` to re-install all missing resources.

I carry out the recommendation given in the Alert:

julia>using Pkg; 
julia> Pkg.instantiate()

Why are some packages updated and others not?
Any rule to follow to discretize between packages with the ability to update and those that do not?!
