Step 6: Activate the Installation
You don't have to restart your terminal session for the changes to take effect. You can simply run source ~/.bashrc command to activate the installation from the same terminal session.
root@cyberithub:~# source ~/.bashrc
(base) root@cyberithub:~#
Step 7: Check Info
To check complete information about Anaconda installation, you can use conda info command as shown below.
(base) root@cyberithub:~# conda info

active env location : /root/anaconda3
shell level : 1
user config file : /root/.condarc
populated config files :

Step 8: List Installed Packages
If you want to check the list of installed packages then use conda list command as shown below.
(base) root@cyberithub:~# conda list
# packages in environment at /root/anaconda3:

anyio 2.2.0 py39h06a4308_1
...........................
Step 9: Update Anaconda
If you want to update Anaconda then you need to run conda update conda command as shown below.
(base) root@cyberithub:~# conda update conda Collecting package metadata (current_repodata.json): done Solving environment: done ## Package Plan ## environment location: /root/anaconda3 added / updated specs: - conda The following packages will be downloaded: package | build ---------------------------|----------------- conda-4.12.0 | py39h06a4308_0 14.5 MB conda-package-handling-1.8.1| py39h7f8727e_0 889 KB ------------------------------------------------------------ Total: 15.3 MB The following packages will be UPDATED: conda 4.10.3-py39h06a4308_0 --> 4.12.0-py39h06a4308_0 conda-package-han~ 1.7.3-py39h27cfd23_1 --> 1.8.1-py39h7f8727e_0 Proceed ([y]/n)? y Downloading and Extracting Packages conda-package-handli | 889 KB | ################################################################################################################## | 100% conda-4.12.0 | 14.5 MB | ################################################################################################################## | 100% Preparing transaction: done Verifying transaction: done Executing transaction: done
Step 10: Uninstall Anaconda 3
Once you are done using Anaconda 3 then you can choose to uninstall Anaconda 3 by following below steps.
a) Remove Anaconda 3 directory
In the first step you need to remove anaconda3 directory by using rm -rf ~/anaconda3 command as shown below.
(base) root@cyberithub:~# rm -rf ~/anaconda3/
b) Edit .bashrc
Then open .bashrc file using nano editor and remove below lines. Then save the file using Ctrl+X.
# enable programmable completion features (you don't need to enable
# this, if it's already enabled in /etc/bash.bashrc and /etc/profile
# sources /etc/bash.bashrc).
#if [ -f /etc/bash_completion ] && ! shopt -oq posix; then
# . /etc/bash_completion
#fi
# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$('/root/anaconda3/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; then
eval "$__conda_setup"
else
if [ -f "/root/anaconda3/etc/profile.d/conda.sh" ]; then
. "/root/anaconda3/etc/profile.d/conda.sh"
else
export PATH="/root/anaconda3/bin:$PATH"
fi
fi
unset __conda_setup
# <<< conda initialize <<<
c) Remove hidden directory
You can also remove hidden .conda directory from the User's home location using rm -rf ~/.conda command as shown below.
(base) root@cyberithub:~# rm -rf ~/.conda
d) Reload the Bash Shell
Finally refresh the bash shell using source ~/.bashrc command to reflect the recent changes.
