The instructions for installing on any version of the desktop client on Ubuntu are wrong and potentially damaging to client’s computer systems.
The offending line is —
sudo sh -c "echo ‘deb http://download.opensuse.org/repositories/isv:/ownCloud:/desktop/Ubuntu_19.10/ /’ > /etc/apt/sources.list.
The opening double quote in front of the word echo is not matched by a closing double quote
Writing to a file called sources.list. will not work, the file you want is sources.list (no trailing dot)
Redirecting output from an echo command with only a single > overwrites the sources.list file, getting rid of all the existing content - which means the apt command cannot be used to do any further updates of the OS after running this incorrect command. If you want to add an additional source to the list you must use two arrows, >> to append to the file - not overwrite it.
So the correct line is ----
sudo echo ‘deb http://download.opensuse.org/repositories/isv:/ownCloud:/desktop/Ubuntu_19.10/ /’ >> /etc/apt/sources.list
Can this be fixed please?
