How can I install clang on Ubuntu 18.04 LTS Bionic?
6 Answers
clang-6.0
is (at least currently) the default version of clang
on Bionic:
$ apt-cache depends clang
clang
Depends: clang-6.0
Breaks: <clang-3.2>
Breaks: <clang-3.3>
Breaks: <clang-3.4>
Breaks: <clang-3.5>
Replaces: clang
Replaces: <clang-3.2>
Replaces: <clang-3.3>
Replaces: <clang-3.4>
Replaces: <clang-3.5>
$ apt-cache policy clang-6.0
clang-6.0:
Installed: 1:6.0-1ubuntu2
Candidate: 1:6.0-1ubuntu2
Version table:
*** 1:6.0-1ubuntu2 500
500 http://ca.archive.ubuntu.com/ubuntu bionic/universe amd64 Packages
100 /var/lib/dpkg/status
So, you just enable the universe repository and then install clang
- either from the software store or from the command line using
sudo apt update
sudo apt install clang

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-6.0 (>= 6.0~) but it is not going to be installed E: Unable to correct problems, you have held broken packages.– BluetakeJul 23, 2018 at 2:33

1@steeldriver using the it I am getting the following error clang : Depends: clang-6.0 (>= 6.0~) but it is not going to be installed E: Unable to correct problems, you have held broken packages. How to fix it ? Aug 1, 2018 at 9:10

@NithinVarghese that's a rather generic error - there are some suggested fixes in this previous question Unable to correct problems, you have held broken packages among others Aug 1, 2018 at 15:55
Adding to @steeldriver's answer, clang
is a dependency package providing the default clang version, which is 6.0 in Bionic.
You may have better luck installing the clang-6.0
package directly:
sudo apt-get update
sudo apt-get install clang-6.0

@NithinVarghese You might need to ask your own question then showing the errors that you are getting. I have a 18.04 LTS installation and I just barely installed it this way and it worked fine. Without telling us errors, it is nearly next to impossible for us to guess what problems you are having during the installation.– TerranceAug 6, 2018 at 19:39
You can install clang-6.0
on Ubuntu 18.04 using official LLVM repository.
wget -O - https://apt.llvm.org/llvm-snapshot.gpg.key | sudo apt-key add -
sudo apt-add-repository "deb http://apt.llvm.org/bionic/ llvm-toolchain-bionic-6.0 main"
sudo apt update && sudo apt install clang-6.0

1I've tired this method before and it was futile as others. Do you have any clue what can be the cause of this Aug 6, 2018 at 18:30

I have tried and it worked for me. Can you disable other repos and try again ?– KK PatelAug 6, 2018 at 18:31
You might be missing some necessary channels from sources.list
.
Step 1: Backup your repositories and remove repository lists other than sources.list
.
Step 2: Do sudo gedit /etc/apt/sources.list
and make it look like this:
deb http://archive.ubuntu.com/ubuntu bionic main multiverse restricted universe
deb http://archive.ubuntu.com/ubuntu bionic-security main multiverse restricted universe
deb http://archive.ubuntu.com/ubuntu bionic-updates main multiverse restricted universe
Save and exit.
Step 3: Update your repository:
sudo apt update
Step 4: Install clang-6.0
:
sudo apt install clang-6.0
You can do as users above shared
sudo apt-get install clang-6.0
just that i want to pay your attention to this interesting document : LLVM Debian/Ubuntu nightly packages
to get a complete vision how to install nightly packages.
Actualize by latest versions of the compiler:
sudo apt-get update
# sudo apt-get install clang-9
sudo apt-get install clang-10
apt-cache policy clang clang-6.0 clang-5.0
sudo apt install clang-6.0
...sudo apt install clang-6
. You can also dosudo apt install clang-7
andsudo apt install clang-8
