Steam doesn't start after upgrade to Ubuntu 16.04 - Ask Ubuntu

after upgrade ubuntu 16.04, steam doesn't start. when execute command line, following error:

$ steam running steam on ubuntu 16.04 64-bit steam_runtime enabled automatically grep: symbol lookup error: grep: undefined symbol: pcre_jit_stack_alloc grep: symbol lookup error: grep: undefined symbol: pcre_jit_stack_alloc grep: symbol lookup error: grep: undefined symbol: pcre_jit_stack_alloc installing breakpad exception handler appid(steam)/version(1459463254) 

i upgraded 14.04 lts 16.04 lts , wasn't able start steam. started (i mean, 'steam' continued running), nothing happened after few seconds.

for me, workaround found run steam commandline with:

ld_preload='/usr/$lib/libstdc++.so.6' steam 

---

non-essential information below.

steam provides "mini distribution" it, called steam runtime, isn't doing complete job somehow clashes system c++ standard library and/or other libraries. during experiments had complaint of system libreadline6 <-> steam runtime libtinfo5. after manually unpacked steam runtime tarball package under steam directory overwrite had there, changed described in problem (pcre_jit_stack_alloc).

an interesting tidbit before found solution above, able start steam downloaded upgrade disabling steam runtime temporarily export steam_runtime=0. steam wouldn't run first step forward. tried installing system equivalents of 32-bit libraries required, didn't finish / working.
