bug#53459: error while installing with existing partitions

[-- Attachment #1: Type: text/plain, Size: 1018 bytes --]

Hi, 

I was trying to get guix installed on my x86_64 machine. (icore 3, 16Gb
RAM, 1TB ssd, ethernet working, using the guix curses installer)

Originally I tried as the only distribution in the system, but grub-efi
wouldn't get installed or recognised by the bios on boot.

Instead I decided to install debian on the first 500Gb and guix on the
second half. My idea is that by sharing the boot/efi partition and
debian managing the boot I would be able to boot guix as well

Debian created the following partitions
 1 537mb fat32 /boot/efi
 2 512mb ext2 /boot
 3 500GB encrypted volume


Then with guix I manually added the 4th partition as encrypted volume
with / mount point.

After the guix installer ask for the password for the new encrypted volume, I'd see the following error:

```
ice-9/eval.scm:159:9: Throw to key 'match-error' with args '("match" "no matching pattern" (#f ext4))'
```

I have attached a literal screenshot with the whole backtrace.

Any suggestions on how to go forward?

Thanks,

Nestor

bug#53459: Update: Tried non efi, independent boot partition and custom boot entry in debian

[Néstor Arocha]

Hi,

I forgot to mention that I am working with current stable guix 1.3.0

I also tried a few things:
 * Manual installation doesn't trigger the error at all, but the end result is that it won't boot like before
 * an independent boot partition on top of a shared /boot/efi didn't make any difference
 * Trying to install guix with the boot-grub loader rather than efi didn't work at all and the boot installed errored

But I am happy to say that (after standard guix install) adding the entry in grub manually in debian
did work:

```
menuentry "Guix" {
   insmod part_gpt
   insmod chain
   set root='(hd0,gpt1)'
   chainloader /EFI/Guix/grubx64.efi
}
```

and then running update-grub

For some reason it asks for the encryption password twice.

retitle 43459 installer: uuid->string failure backtrace (again)
merge 54480 43459
thanks

This seems to be the same issue as <https://issues.guix.gnu.org/53380>.

> I forgot to mention that I am working with current stable guix 1.3.0 

There's no ‘stable’ Guix; Guix 1.3.0 is just a snapshot of a particular
version of Guix with a bit of extra testing. It doesn't receive
bugfixes.

I recommend trying the latest installer instead of the 1.3.0
installer (see <https://guix.gnu.org/en/download/latest/>).
Since 53459 appears to be the same issue and it appears to
have been resolved, it would seem likely that it has been
fixed in the latest installer.

Unfortunately, the full conversation of 53380 is not available, so I'm
not sure if it has actually been addressed ...

Greetings,
Maxime.

Make sure the computer's boot process is configured to the correct mode
-- UEFI or BIOS (sometimes called ‘Legacy mode’).  Which of the two
you want depend on what exactly you are doing.

What dou you mean with ‘doesn't get recognised by the bios on boot’ --
what exactly does the boot process say?

About ‘grub-efi wouldn't get installed’ -- this is rather vague, do you
have some kind of error message or something?

Also, it would be useful to see the actual system configuration
(the (operating-system [...])).

Greetings,
Maxime.

BIOS doesn't have a legacy mode option that I could see (motherboard MSI
MPG z490 gaming plus). So for this system I am stuck with uefi (I think)

After installing guix when it tells me to reboot, the next boot will
simply not boot. There is no error within guix or any indication of a
problem.

Even now when running `guix system reconfigure /etc/config.scm`

the output says:

```
building /gnu/store/gh6k581m0qddzrc601rj49j0v3fyim5x-install-bootloader.scm.drv...
guix system: bootloader successfully installed on '/boot/efi'
The following derivation will be built:
   /gnu/store/siwn6q6kyxacjz1wdkwd8lm6w18606g8-upgrade-shepherd-services.scm.drv
...
```

But the system still boots with debian's grub first which then I can
chain to guix's grub. I'd expect guix to override the boot or at least
to see the option in the bios

Hello,

> ice-9/eval.scm:159:9: Throw to key 'match-error' with args '("match" "no matching pattern" (#f ext4))'

This is very likely fixed by: ab974ed709976d34917c8f6f9e5cc0004547af45.

Thanks,
