I’m currently trying to install “eclipse-cpp-2020-06-R-linux-gtk-x86_64.tar.gz” onto Kubuntu 20.04 using the instructions given on “linuxconfig-dot-org-eclipse-ide-for-c-c-developers-installation-on-ubuntu-20-04”
However, I’m hitting a roadblock at step 3 (the eclipse archive is located in ~/Downloads):
"Extract the Eclipse package downloaded in the previous step. Here we assume that the package has been downloaded into the Downloads directory.
Extract the package into the /opt directory:
$ sudo tar xf eclipse-cpp-2020-6-R-linux-gtk-x86_64.tar.gz -C /opt"
When I Copy, Paste, and execute the command shown above (to Konsole which is focussed on the ~/Downloads folder) the system displays the following:
$ sudo tar xf eclipse-cpp-2020-6-R-linux-gtk-x86_64.tar.gz -C /opt
[sudo] password for kub:
tar: eclipse-cpp-2020-6-R-linux-gtk-x86_64.tar.gz: Cannot open: No such file or directory
tar: Error is not recoverable: exiting now
Folder /opt does exist and is owned by root. The archive is 240.6 MiB, according to Dolphin so I haven’t erroneously saved just an HTML page.
Could someone please suggest where I have gone wrong and suggest a possible route forward ?
Thanks in advance,
