How does one fix the issue of not writable paths with conda?

Why do I see the following error when using conda (usually when installing packages or making new envs) and how do I fix it:

check if a path is writable:

if [ -w "./.conda" ]; then echo "WRITABLE"; else echo "NOT WRITABLE"; fi

if it is not writable, change writability to anybody:

chmod 775 ./.conda

If you are curious of existing file permission:

ls -lha outputs the set of access right of current locations, where d refers to current directory. Eg: drwxr-xr-x :

each digit refers to right for User, Group and Global respectively. For the above example, rwx means current user can read,write and execute; r-x for both group and global, which means they can read and execute only.

chmod is used with a 3-digit commands, each digit refers to one combination of the read, write, execute access for the above three types of identity.

755 means rwx for current user, and r-x for Group and Global.
