Looks like the URL needs to be updated.

@evverx @diederikdehaas Do you know offhand what should be the new location?

[evverx]

Looks like the fuzz targets are no longer installed to /usr/bin. I think this script can be safely removed because that local fuzzing infrastructure was removed when lxc switched to meson. CIFuzz runs the fuzz targets with those corpora on every PR these days anyway.

@hallyn maybe you tried to get someone else's attention?

@hallyn maybe you tried to get someone else's attention?

Could be - apologies if so. I was looking at the changelog which listed Signed-off-by: Diederik de Haas didi.debian@cknow.org

[hallyn]

(but I do see that it was not actually relevant to the test itself, so in any case a bad callout. Sorry)

[diederikdehaas]

No worries :)
I did make changes, but that was without knowing or understanding the full tests. So I can't provide any useful input here.
