      Attempting to build RetroPie on a fresh Ubuntu 16.04 x64 install, following the instructions from https://retropie.org.uk/docs/RetroPie-Ubuntu-16.04-LTS-x86-Flavor/ exactly, I ran into this:

      Could not successfully build mupen64plus - N64 emulator MUPEN64Plus
      (mupen64plus-core/projects/unix/libmupen64plus.so.2.0.0 not found).
      

      This is presented in the context of a dialog screen while running the Basic Install from the script. Any suggestions?

      Oh, and after I hit enter to continue, it says:

      Could not install package(s): flex bison nasm
      

      and finally

      Please see /home/aron/RetroPie-Setup/logs/rps_2017-04-17_212857.log.gz
      for more in depth information regarding the errors.
      

      I'll see what's there

        Oh gosh, I should have looked first:

        E: Could not get lock /var/lib/dpkg/lock
        

        Et cetera. Seems like I just should rerun the setup script. The lock was probably taken temporarily by a background process checking for updates.

          i also had this problem on ubuntu 16.04.2 32bit and lubuntu 17.04 64bit.

          I installed the emu again from the setup script and both times it worked from there...not sure where the bug is...

            @allow No bug afaik - just apt-get failed to install the requisites as another process was using it.

              but reproducable every time install retropie on ubunt?

              Every time i tried it i got this error. No problem for me, but if it fails most of the time it looks like a bug to me .-)

                It took me three tries. First two times failed with the same error, third time ran all the way through.

                  I also just ran into this on a fresh install of RetroPie on Ubuntu 16.04.2. I have run into it every time this year. Here are some relevant things I've seen from the logs. I'm hesitant to open a bug, though. Installing it manually from the packages menu in the setup script works fine. Anyone else seeing things like this?

                  CXX _obj/osd/osd.o
                  nm _obj/asm_defines/asm_defines.o | awk -v dest_dir="../../src/asm_defines" -f ../../tools/gen_asm_defines.awk
                  AS  _obj/device/r4300/x86_64/dyna_start.o
                  /bin/sh: 1: nasm: not found
                  Makefile:694: recipe for target '_obj/device/r4300/x86_64/dyna_start.o' failed
                  make: *** [_obj/device/r4300/x86_64/dyna_start.o] Error 127
                  make: *** Waiting for unfinished jobs....
                  rm ../../src/asm_defines/asm_defines_nasm.h

                    Update, I looked more closely at nasm entries in the log. The step:

                    Installing dependencies for 'lr-mupen64plus' : N64 emu - Mupen64Plus + GLideN64 for libretro
                    

                    comes after mupen64plus (non-libretro). The nasm package is installed as part of that step which is why it's missing earlier and fails.

                      That was fast. Fixed in: https://github.com/RetroPie/RetroPie-Setup/commit/a3880c22ff6e7d0fbfade633a9fb4574ff97cf1e

                          @aron i got same on compiling mupen64plus (standalone) on Tinker with missing error from specific build folder
                          /home/pi/RetroPie-Setup/tmp/build/mupen64plus/mupen64plus-core/projects/unix
                          I ve added a copy of the libmupen64plus.so.2.0.0 in the folder over winscp just asap scriptmodule created the build subfolder(s) and it compiled fine without an error.
                          Hope that work around helps
