Thank you Stefan and Alan in another email.

With the hint, I find out the `async-bytecomp-package-mode` is turn on
by the package `helm-core`. So it is a bug of `async-bytecomp` maybe,
and I will report it the package author.

Sorry for the misleading information in the orignial email.

&gt;&gt; When I try to install packages from the Package Menu or the command of
&gt;&gt; package-install since about two weeks ago, it reports the error:
&gt;&gt; ```
&gt;&gt; error in process sentinel: async-when-done: Invalid read syntax: "#<"
&gt;&gt; error in process sentinel: Invalid read syntax: "#<"
&gt;&gt; ```
&gt; Stefan, any thoughts?

IIUC the above error involves some part of the `async` package.
Could you give a bit more information about how you hooked `async` with
`package`?
