@vanhauser-thc fyi to fix sometime, i was trying to debug ci issue with aflplusplus_optimal and aflplusplus_eclipser, but ran into this. should be something minor in /etc/apt/sources.list.

[inferno-chromium]

don't see clang-12 in there - https://apt.llvm.org/xenial/dists/

[yifengchen-cc]

https://github.com/google/fuzzbench/blob/master/fuzzers/aflplusplus_optimal/builder.Dockerfile#L22 change llvm-toolchain-xenial to llvm-toolchain-xenial-12 can fix this problem

nope it does not, see my last comment, there is no 12 support in https://apt.llvm.org/xenial/dists/

That's weird, I used this method to create a local experiment successfully. It has llvm-toolchain-xenial-12 in https://apt.llvm.org/

Precise, Quantal, Raring, Saucy, Utopic, Artful, Cosmic, Eoan and Trusty are no longer supported by Ubuntu. Repo remains available

Feb 01st 2021 - Snapshot becomes 13, branch 12 created

that why it breaks. happened too when snapshot became 12 from 11. there is no -X branch until the snapshot switched to Y... will fix it :)

[vanhauser-thc]

ok ... they switched snapshot to provide 13, but did not create 12. so there is currently no 12 available. what do? I'd propose waiting for a few days and see if they add it, and if not downgrade to 11?

[vanhauser-thc]

Now it is there - will update with the next experiment (Friday)

[inferno-chromium]

this is fixed with @vanhauser-thc cl
