scm_lreadr error on guix pull

scm_lreadr error on guix pull

[Phil Beadling]

Hi all,

I'm seeing this error doing a guix pull from a single linux account.  All
other linux accounts are operating fine on guix pull on the same machine.

I tried removing ~/.config/guix for this account, but this made no
difference.

The error is comming (I think) from invoke/quiet receiving a non-zero
return code.

Any ideas?

In procedure scm_lreadr:
/gnu/store/av5gc90fyivafhr54c49519ldxbrrfr0-module-import/guix/build/utils.scm:715:1:
illegal character in escape sequence: #\return

Thanks,
Phil.

I cannot reproduce this.

Could you please provide the output of “guix describe”?  What Guix 
are you using after deleting ~/.config/guix?

I also have a local guix channel but have no reason to think that is the
issue at the moment.

I can only reproduce this issue on a single user account.  All the other
accounts I've tried (on the same server) , report exactly the same commit
from guix describe yet do not show the issue.

When deleting the current profile, I end up using the same version anyway.
Note I do have the guix repo anchored at
675540892719387e1e4e76f097ff8e4ee4b559f7 in the channel setup.

Some more info from me - I've removed my local channel and reproduced using
only guix:

$ guix pull

There's also a bit more info I forgot to include in the stdout.

I have tried to do a "guix pull --rollback" - that didn't seem to help.

This commit is from May 2021.  So it is weird that you pull this commit.

All the best,

Yep - I keep all my accounts in lockstep and move them every few months -
it has been a while since I've done this, but the commit id shouldn't
matter - I should be able to set that to any commit id and have it work.
The other accounts are locked to the same commit id and they have no issue.

Also if I force to current head it still errors (see below).

I've also tried clearing the ~/.cache/guix directory and deleting the
/var/guix/profiles/per-user/<USERNAME> directory - no luck, alas.

Is there anyway to obliterate Guix setup for this one user account and then
start from scratch.  Given that all other users on the same server don't
see this problem, that's probably the nuclear option?  There's nothing
precious in terms of rollbacks that I couldn't afford to lose - espically
given the rollbacks seem to be broken too.

Thanks for the suggestion - I think I did a similar test which has solved
the initial problem, but there is an underlying problem I'm still perplexed
by.  I will try your suggestion too, but below is my progress so far.

Say we have 2 users:
good-account
bad-account

One bad account I did:
cd
mkdir vault
mv * vault/
mv .* vault

logout/login

Then with a bare account I did a guix pull and it worked!

I thought I'd solved the problem - presumably some stale setting somewhere
in bad-account's config/env/etc - but then I tried a 'guix environment'
command and noticed that the bad-account was still trying to build things
the good-account would take from the local gnu store.

I isolated an example below - the 2 accounts retrieve the same
channels/branches/commit id.  The good-account picks up the version
previously built in the store, but the bad account (presumably) comes up
with a fingerprint that disagrees with the other account and decides to
build from scratch.

There is probably is still some rogue config operating on behalf of the
bad-account that produces the different fingerprint - but no idea what this
could be?

Did you run “./pre-inst-env guix pull“ once with the bad account?
Because for instance ’localstatedir’ or ’sysdir’ could be different; or
something else.  That’s why I am asking ’which guix’ and ‘readlink
$(which guix)’ because then the derivations can be checked to find the
differences. :-)

All the best,
simon
