Hi, I think this mail should reach Keifer.

@ Keifer please post the output of:

It should be 'Debian GNU/Linux 10'

apt update && sudo apt full-upgrade
would install missing packages.

Then read what Ben wrote about 'update-ca-certificates'.

You'll see this because your system doesn't trust the cert chain.



You're not seeing a certificate warning because you've got output suppressed
(the -q in wget's arguments)



If you run



    wget https://deb.torproject.org/torproject.org/
A3C4F0F979CAA22CDBA8F512EE8CBC9E886DDD89.asc



I suspect you'll see the certificate warning.



You need to fix that before anything suggested here is going to work - if the
cert chain isn't trusted then apt isn't going to access the repository's
indexes, and so won't even see what packages are there, much less install
them.



As apt didn't grab an updated version for you (which may be due to other repo
misconfigurations) you probably want to grab and install the cert manually




    # Verify that this gives a cert warning

    curl https://deb.torproject.org/torproject.org/



    curl -k --output "/tmp/ISRG_Root_X1.crt"  "https://letsencrypt.org/certs/
isrgrootx1.pem.txt"

    sudo mv /tmp/ISRG_Root_X1.crt /usr/local/share/ca-certificates/

    sudo update-ca-certificates



    # Now try again

    curl https://deb.torproject.org/torproject.org/



If that final curl now works, run apt-get update and you should find apt no
longer complains about the tor repo
