Step 1

apt install clang-11

fails with error

Step 2

apt install libclang-cpp11

fails with error

Step 3 apt install libllvm11

  • We don't know your OS & release for starters, and for best help you should provide full output as it looks like you're trying to hide details and without some of those details provided our ability is limited in what we can offer (we can't do command searches for packages until we know OS & release details) – guiverc Apr 29 '21 at 05:48
  • Where you're getting clang-11 from may also help, ie. apt-cache policy clang-11 – guiverc Apr 29 '21 at 05:55
  • I have attached the output . Source of package installation is pretty standard I found on net. – Genie Apr 29 '21 at 06:04
  • You are trying to use a Debian Buster/11 package on an old Ubuntu? Are you surprised packages won't align correctly? clang-11 is available in Ubuntu repositories for later releases (clang-10 is built for bionic). If you need to use your release, I'd suggest looking for an appropriate source for clang-11 for Ubuntu & not use one packaged for another OS & release, and please use {code} tags not text-quoting for command pastes. – guiverc Apr 29 '21 at 06:12
  • Thanks a lot. The error is of using wrong source . With bionic problem got resolved. – Genie Apr 29 '21 at 07:29
