<pre>Beginning yesterday, or within the last couple days, many clang-packages, such
as clang-11, clang-5, etc. from llvm began to fail their installation. This
was been reported to me by others as well.
It seems to be specific to Ubuntu 16.04 (named Xenial), and Docker (although
probably also non-Docker).
The same installations worked fine last week.
Example:
+ sudo -E apt-get -o Acquire::Retries=3 -yq install clang-11 libstdc++-9-dev

Reading state information...
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-11 : Depends: libclang-common-11-dev (=
1:11.1.0~++20210204122740+1fdec59bffc1-1~exp1~20210203233413.161) but it is not
going to be installed
E: Unable to correct problems, you have held broken packages.
More info:
The following were also installed:
sudo -E apt-add-repository -y "ppa:ubuntu-toolchain-r/test"
sudo -E apt-add-repository "deb <a href="http://apt.llvm.org/${LLVM_OS}/">http://apt.llvm.org/${LLVM_OS}/</a>
llvm-toolchain-${LLVM_OS}-${LLVM_VER} main"</pre>
