Cannot open Visual Studio Code

Question

I've installed VS Code on my laptop with Ubuntu 16.04 LTS. I've tried multiple installation methods with identical results; most recently, I followed the "new" instructions from Cactux here. I've tried opening the application two ways to no effect.

• When I open the program from 'Applications', the icon shows in the launcher for approximately 15 seconds and then disappears. No error pops up.
• When I open a terminal and type code, the command does nothing and I get a new prompt in less than a second.

I'm struggling with what to try since I'm relatively new to Linux. which code yields /usr/bin/code, which is a bash script. This is where I get outside my depth.

Contents of script

/usr/bin$ cat code

if [ "$(id -u)" = "0" ]; then
    for i in $@
    do
        if [[ $i == --user-data-dir || $i == --user-data-dir=* || $i == --file-write ]]; then
            CAN_LAUNCH_AS_ROOT=1
        fi
    done
    if [ -z $CAN_LAUNCH_AS_ROOT ]; then
        echo "You are trying to start vscode as a super user which is not recommended. If you really want to, you must specify an alternate user data directory using the --user-data-dir argument." 1>&2
        exit 1
    fi
fi

if [ ! -L $0 ]; then
    # if path is not a symlink, find relatively
    VSCODE_PATH="$(dirname $0)/.."
else
    if which readlink >/dev/null; then
        # if readlink exists, follow the symlink and find relatively
        VSCODE_PATH="$(dirname $(readlink -f $0))/.."
    else
        # else use the standard install location
        VSCODE_PATH="/usr/share/code"
    fi
fi

ELECTRON="$VSCODE_PATH/code"
CLI="$VSCODE_PATH/resources/app/out/cli.js"
ELECTRON_RUN_AS_NODE=1 "$ELECTRON" "$CLI" "$@"
exit $?

Any help or suggestions are appreciated.

Answer 1

I had the same problem described here, new install of Ubuntu 18.04 LTS. I installed VS Code from conda.

Discovered that if you run the following

code --verbose

It will tell you what is going on with Code. In my case

code --verbose
[main 20:19:26] Startup error: 
Error: EACCES: permission denied, mkdir '/home/<user>/.config/Code/CachedData'

sure enough the folder ~/.config/Code had root access permissions for some reason. Deleted the folder using sudo.

rm -rf /home/<user>/.config/Code 

Tried again to run code and it working fine.

Answer 2

I had the same problem. Like Robin G and Nezir suggested I realized that the owner of the /home/user/.config/Code directory is the "root". However, You could just change the ownership of that directory instead of removing it.

sudo chown -R $USER "$HOME/.config/Code"

"-R" option is needed to recursively change the ownership of all the files and directories under the target directory.

After this the Visual Studio Code v. 1.27 on Ubuntu 18.04 works as it is supposed to on my machine.

Answer 3

Debug the bash with the correct command

To debug you should use following command:

bash --debugger `which code`

This will run the bash script line per line. To go to the next line simply type n and return. Post the output than we will see more.

Installing via snap (for Ubuntu versions > 18.04)

BTW Ubuntu 18.04 LTS (Long term release) now supports code directly and you can install it via snap package:

Show version and info of ubuntu supported snap:

snap info code

and to install it

sudo snap install code 

I personal prefer to install it via apt. Therefore follow this instruction from microsoft:

Installing VS Code

curl https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.gpg
sudo mv microsoft.gpg /etc/apt/trusted.gpg.d/microsoft.gpg
sudo sh -c 'echo "deb [arch=amd64] https://packages.microsoft.com/repos/vscode stable main" > /etc/apt/sources.list.d/vscode.list'

This will download the gpg key and copy and make the apt files. Then you can simply update and install vs code:

sudo apt-get update
sudo apt-get install code

• The advantage of this installation method is that you can simple update vscode using the apt-get update command. Works fine and I use vs code with the vim plugin for over 2 years (c, c++, python, md, latex, html, javascript ...).

Answer 4

Try in terminal

code --user-data-dir

Worked for me.

Answer 5

In my case when I ran code --verbose the error was:

Error: ENOSPC: System limit for number of file watchers reached, watch '/snap/code'

So I increased number of file watchers to its maximum by modifying /etc/sysctl.conf and adding this to at the end of the file:

fs.inotify.max_user_watches=524288

Then I had to run this command to load the value in system:

sudo sysctl -p

Now I can run VScode with no issues

Answer 6

I had the similar problem here:

https://github.com/Microsoft/vscode/issues/55774#issuecomment-412774473

and fixed it with "delete the /home/user/.config/Code folder"

Thank you!

Answer 7

Open your terminal and run the following commands:

1. sudo rm -rf /home/your_username/.config/Code

   (Replace your_username with your actual username.)

   Then provide your password and press Enter.

2. code --verbose

Answer 8

VS code may silently fail to open if you don't have required dependencies.

From this page:

sudo apt-get install -f # Install dependencies

Answer 9

code --verbose

alone did the trick for me when Code failed to start (got jammed) after X system crash. However, the files opened were not the most recent, but some ancient ones.
