Unable to install DFINITY Canister SDK on Ubuntu

I'm following the steps found here to install DFINITY Canister SDK.
When I run the below command, directory dfx (under /bin) is not created and subsequently the dfx command is not recognized:

adel@adel-VirtualBox:~$ sh -ci "$(curl -fsSL https://sdk.dfinity.org/install.sh)"

Command 'dfx' not found, did you mean:

  command 'fx' from snap fx (11.1.0)
  command 'dfix' from snap dfix (0.3.5)
  command 'dx' from deb dx (1:4.4.4-12build2)
  command 'dex' from deb dex (0.8.0-2)
  command 'dfc' from deb dfc (3.1.1-1)
  command 'df' from deb coreutils (8.30-3ubuntu2)

See 'snap info <snapname>' for additional versions.

adel@adel-VirtualBox:~$ cd /bin
adel@adel-VirtualBox:/bin$ cd dfx
bash: cd: dfx: No such file or directory

Below is my Ubuntu version:

adel@adel-VirtualBox:~$ lsb_release -a

Solution

From the output of the install command it looks as if dfx is installed in /home/adel/bin/dfx. Can you verify that:

dfx is indeed there?

test -e /home/adel/bin/dfx && echo yay found it || echo oh no

If not, it looks as if the install didn't work.

If yes, you can run it directly:

"$HOME/bin/dfx" --version

Check that your path includes "/home/adel/bin"

echo "$PATH" | tr : "\n" | grep "$HOME/bin"

If not, you can add it with:

echo 'export PATH="$PATH:$HOME/bin"' >> "$HOME/.bashrc"

. "$HOME/.bashrc"

dfx --version
