Hi,

Looks like you're on windows. I ran it on windows actually =x.

Which version of auto-package-update you're using?
Have you tried running package-refresh-contents before updating? Does this error occur only for ack-and-a-half ?

[spaceotter]

This also occurs on linux. I use both. Version 20150125.1550, the lastest in melpa. The apu--package-up-to-date-p works on other packages, it seems to have a particular problem with ack-and-a-half.

[rranelli]

Alright. I will install ack-and-a-half over here and see what I can find.

If nothing works I will handle the exception and notify the user which packages could not be updated.

[spaceotter]

You may have trouble installing ack-and-a-half. The package has been abandoned for a rewrite and is no longer in melpa. I will just remove it.

[rranelli]

Just found it out now over here

While you're at it, I really recommend ag.el. That's what I use for searching text. Not sure if it would work on windows though.
