I just tried to install tor browser.
I downloaded and signature-checked from
https://www.torproject.org/download/download-easy.html.en
When running tar -xvfJ tor-browser-linux64-7.0.4_en-US.tar.xz
I was met with:
tar: J: Cannot open: No such file or directory
tar: Error is not recoverable: exiting now
Afterwards I decompressed via the file manager.
Following this guide:
https://cialu.net/install-tor-browser-on-linux-and-set-up-a-launcher/
I want to set-up a launcher. But When entering
sudo mv tor-browser_en-US /opt
I get
mv: inter-device move failed: ‘tor-browser_en-US’ to
‘/opt/tor-browser_en-US’; unable to remove target: Is a directory
Any help on problem and/or solution?
