Steam cannot set up steam data

You could try this:

mv ~/.steam/steam/* ~/.local/share/Steam/
rmdir ~/.steam/steam
ln -s ../.local/share/Steam ~/.steam/steam
rm -rf ~/.steam/bin

Which is essentially doing what the steam executable is trying to do, but failing.

I know it's been a while and you've probably solved the problem already, but here is a fix that also works.

This error can result if you HAD Steam installed, then did a "nuke and pave" to re-install your system but had /home on a different partition. When you reinstall Linux, your home directory is intact, including your Steam settings, which are in the ~/.steam directory. Remove the directory by opening the terminal and typing:

cd ~
rm -rf .steam

This will delete the settings folder, and Steam should install normally.

considering that you had already the ff:

1. /home/.steam
2. steam launcher

Steps

1. at terminal:

   $ mv ~/.steam/steam/* ~/.local/share/Steam/
   

2. using GUI, goto .steam folder, by default its located at /home/.steam

3. inside the ./steam folder, delete the steam folder.. yeah, theres still another steam folder inside the ./steam folder.. just delete it.

4. press Ctrl+T at terminal.. $ steam --reset then hit enter

5. your steam should working and updating.
