Hi,

Right now, I have an empty store item : openssh-8.9p1.
Could be the result of brutal shutdown (laptop battery)…

I think this might be caused by <https://issues.guix.gnu.org/58035>.

guix gc --verify=repair,contents
guix build --repair openssh
guix build --check openssh
guix build -d openssh
guix gc --optimize
guix gc -D /gnu/store/ffp49k0wci7h36lk38lasx4r5lc4i7iv-openssh-8.9p1

But nothing worked.

$ sudo guix build --repair $(guix build openssh --no-grafts)

then the grafted version:

$ sudo guix build --repair $(guix build openssh)

One additional trick: openssh is grafted, try repairing the ungrafted openssh first: (though if that works, I don't know how the ungrafted openssh could have been considered valid in the first place).

I read somewhere deleting /gnu/store/.links could be helpful but as I'm
not sure I did not.

Greetings,
Maxime

It might not be helpful, but it can't be harmful (except for more disk usage, but running a 'guix gc --optimize' afterwards should address that). (If you try this, first delete .links, then do the "guix build --repair", in that order.)
