"error: libcurl.so: cannot open shared object file: No such file or directory"
... so you need to install it.
That would need something like that on my system, Debian
"apt-get install libcurl3:i386" (for 64 bit installations)
"apt-get install libcurl3" (for 32 bit installations)

In case installing curl doesn't help, try what we usually do for arch and other newer distros. Arch wiki -> Steam ->Steam runtime issues.
