It appears that ever since LLVM 11 has been tagged for release, the ubuntu
20.04 apt repository seems to be broken.
It seems the non-version packages target version 11, but it's missing.
Version 12 packages are present, but are not the defaults.
Simple repro using Docker image for Ubuntu 20.04:
FROM ubuntu:20.04 AS build-env
RUN apt-get update \
&& apt-get install -y apt-transport-https ca-certificates gnupg
RUN wget -O - https://apt.llvm.org/llvm-snapshot.gpg.key | apt-key add - \
&& apt-add-repository "deb http://apt.llvm.org/focal/ llvm-toolchain-focal
main" -s \
&& apt-get update \
&& apt-get install -y \

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
clang : Depends: clang-11 (>= 11~) but it is not installable
llvm : Depends: llvm-runtime (= 1:11.0-51+0~20200404161639.1~1.gbp214056)
but it is not going to be installed
Depends: llvm-11 (>= 11~) but it is not installable
llvm-dev : Depends: llvm-runtime (=

Depends: llvm-11-dev (>= 11~) but it is not installable
E: Unable to correct problems, you have held broken packages.
The 18.04 image (and llvm-toolchain-bionic) seem to work just fine, but
debian:buster (and llvm-toolchain-buster) return the same errors.
When targeting repo llvm-toolchain-focal-10, the packages install correctly
(w/ version 10). Interestingly, using llvm-toolchain-focal-11 gives the
same results as llvm-toolchain-focal-10 (it installs LLVM & Clang version
Is this a known issue?
