bug#56012: guix pull fails. cannot build guix-package-cache.drv.

[vidak]

hey all.

vidak here.

i cannot get `guix pull` to work for me.

i am having issues getting the package-cache.drv to build.

i was homeless, and unable to update my workstation for about... a
month?

here are some related issues:

https://issues.guix.gnu.org/52650

https://issues.guix.gnu.org/47949

https://issues.guix.gnu.org/33661

i can trace the output logs to this commit, which seems to be the
offending one. 

commit -- 3b50b327f7cf3226a0e37bc6afa1e921c9c075f7

```
~ $ cat
/var/log/guix/drvs/zk/1hgixlv3gccgbriad7nr2xyla8bbzx-guix-package-cache.drv
(repl-version 0 1 1)
Generating package cache for
'/gnu/store/1mzdd7rf9r34xiibcs1gpjsf7jkh6a0r-profile'...
(exception unbound-variable (value #f) (value "Unbound variable: ~S")
(value (libpng-1.2)) (value #f))
```

i can `guix pull --commit` to before 31-05-2022, but i cannot seem to
pull to anything later than that date.

can anyone help me?

thanks so much in advance.

This has been reported a few times ;) That was the date when the libpng v1.2 package was removed. However, the guix-gaming channel still references it, so you'll need to remove or patch it for now I guess...

(I think the reason this is such a commonly reported problem is that that exception didn't even give a location! We really should improve the error messages in Guile and Guix... I'll make the first 'papercut' issue report on it.)

This is most likely because one of the channels you're using is still refering to libpng-1.2, but it was removed from guix recertly.
