I tried to install from a tarball downloaded from the tor site. But it doesn’t start. All unpacked files for some reason have root rights, and changing the rights of each file is tedious. Although I unpacked in the user directory.But Tor can’t start with root rights.

Do you have gnupg installed? I thought it was always pre-installed.
gpg --auto-key-locate nodefault,wkd --locate-keys torbrowser@torproject.org 12:04:57
gpg: key 4E2C6E8793298290: "Tor Browser Developers (signing key) <torbrowser@torproject.org>" not changed

what does it return?

Try and install from your cache, what I put earlier (here, removed) will not work…
There is also torbrowser-launcher in the official repos which I am using without problems.
