Tor install help

Apparently the Tor browser package in the Pure OS repro is still broken! Great & Wise Mladen please fix.
I attempted the fix elude to here on this forum. When I type /etc/apt/ into the bash I get: “Is a directory”. When I type /etc/apt/sources.list I get : “permission denied”. When I type sudo /etc/apt/sources.list I get: “command not found”.
Can anyone tell me what I am doing wrong?
