I use modules with great pleasure. And it works really fine.

But from time to time, when I come back to my previous hugo site, hugo refuse to run ( `hugo`, or `hugo mod whatever`) and I get module errors (see below).  
I have a simple conf modules (no cache).

Only workaround is to go to the incriminated folder and delete `/var/folders/4y/1tx3_dgs3fb03yt9qn94t_p80000gn/T/hugo_cache/modules/filecache/modules/pkg/mod/cache/`.

Then `hugo mod get -u` works again flawlessly.

I really can’t see any pattern or suspect event.  
Strangely, nothing on the forum, so I suspect it is on my side (Mac OCS 10.14.6) but My Mac works flawelessly other wise (and for any hugo dev).

Have you been doing any `git push -f` by any chane?

Also note that you can do:

```auto
hugo mod clean

```

Or

```auto
hugo mod clean --all

```

I have experienced what you see, but I’m pretty sure that has always been in situations where I have deleted Git refs remotely (e.g. by force pushing).

Mmmm … No, just standard & classic push (I verified).

And for the `hugo mod clean` I’m _pretty_ (but not 100% to be honest) sure I tried it.

I will have an open eye for the next time and have a more accurate report about various commands (sorry for this time not to be more precise).

Thanks for your informations about this

Ah … but I have 2 external modules where I have no control. So may be _they_ have done this force push. Could make sense.

Note that I’m not saying 100% that there isn’t an issue here, and it could also be platform variations, but, luckily for me, that would be an upstream Go issue hopefully improved in the future.
