Installing clang from ubuntu package repository fails

[rashedmyt]

Describe the bug
I have done sudo apt install clang-6.0. The build crashed due to that. The existing clang in ubuntu is not from the ubuntu package repository.

Virtual environments affected

• macOS 10.14
• Ubuntu 16.04 LTS
• Ubuntu 18.04 LTS
• Windows Server 2016 R2
• Windows Server 2019

Expected behavior
Should exit gracefully.

Actual behavior
Exits abruptly with following message

The following packages have unmet dependencies:
 libclang-6.0-dev : Depends: libclang1-6.0 (= 1:6.0-1ubuntu2) but 1:6.0.1~svn334776-1~exp1~20190309042703.125 is to be installed
                    Depends: libclang-common-6.0-dev (= 1:6.0-1ubuntu2) but 1:6.0.1~svn334776-1~exp1~20190309042703.125 is to be installed
E: Unable to correct problems, you have held broken packages.
##[error]Process completed with exit code 100.

Similar error for clang-format:

Run sudo apt-get install clang-format
Reading package lists...
Building dependency tree...
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-format : Depends: clang-format-6.0 (>= 6.0~) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Following https://apt.llvm.org/ doesn't seem to work either

Hi!
I am closing this issue since CLang was preinstalled to Ubuntu images in scope of #104. Feel free to reopen if you still need any help
