Build failure after removing the cache

The module affected

RUST

What is the action to reproduce the bug?

• Purge the build cache
• Build the equivalent of job linux-seco-intel-b68-extra-gcc

What is the result you see?

Job #79601 failed for e81ef83c:

What is the result you expect?

Build succeeds normally

Frequency?

Once, after purging all sstate-cache on the build server.

Tested version

e81ef83c

Do you know any workaround of this issue?

Re-trying the job fixed the build issue (somehow). It looks that something else has populated the cache and the offending job no longer failed.

Do you have a fix for this issue?

Nope
