The repo is cloned successfully though, so not a blocker.

  • Status changed from Confirmed to In Progress
  • % Done changed from 0 to 10

Passing --debug to torsocks in /usr/local/bin/git tells me that the name that can’t be resolved is “amnesia”:

I have no idea why Git wants to resolve the local hostname. I can’t reproduce that on my own sid system (that has nameserver 127.0.0.1 pointing to Tor in case that matters), even if I enable AllowOutboundLocalhost. I’ve tried to make Tails config as close as possible to mine, and I still get the same error. Next step would be to strace the whole thing to understand why Git wants to resolve “amnesia”.

It makes Git command completion very painful, which affects a number of contributors.

Sorry, this part is not resolved, so reopening.

#9 Updated by intrigeri 2017-03-18 10:44:37

  • Status changed from Confirmed to In Progress

The part that’s fixed already is Failed to get capabilities of file `/usr/bin/git' (Operation not supported).

Note that AllowOutboundLocalhost 2 is not enough to fix the other (Unable to resolve) confusing message.

Here’s how to trace Git execution:

sudo sysctl kernel.yama.ptrace_scope=0
sudo apt update
sudo apt install strace
strace git clone https://github.com/micahflee/onionshare

#15 Updated by intrigeri 2017-03-18 10:58:11

Creating /etc/mailname that contains localhost fixes the problem. Now investigating with gdb why is that.
