!!! ERROR !!! Can't unpack x86_64-gcc5 bundle file.

I downloaded the *.run 64 bits. I’m running Opensuse Tumbleweed and got several of the following errors:

tar: Ardour_x86_64-5.5.0/lib/libexpat.so.1: Cannot write: No space left on device

and then the installation stoped and I got:

tar: Exiting with failure status due to previous errors

!!! ERROR !!! Can’t unpack x86_64-gcc5 bundle file.

Press ENTER to exit installer:

System:
Linux nohostname 4.8.6-2-default #1 SMP PREEMPT Thu Nov 3 13:00:34 UTC 2016 (1d89b44) x86_64 x86_64 x86_64 GNU/Linux

Well I suppose let me ask the obvious question, how much free space do you have in /opt ?

   Seablade

Put a little more clearly, the error output said:

    tar: Ardour_x86_64-5.5.0/lib/libexpat.so.1: Cannot write: No space left on device

My root partition was full as hinted by seablade and Paul. I had to schedule a clean up of the /tmp and /var/tmp/ that wasn’t set by the Tumbleweed by default. Something related to systemd as I read in the opensuse forums.
That was all.
Thanks a lot for the answers.

For future reference, there’s a --target option to unzip the temporary bundle to some place other than /tmp if disk-space is scarce there. (see also sh Ardour*.run --help)
