Public bug reported:
I'm working on a Ubuntu 18.04.3 LTS x86_64 machine (fully patched). The
machine has a GNOME3 desktop. Sometimes I sit at the workstation, and
other times I SSH into the workstation.
When sitting at the workstation Git commit signing works. I use 'git
commit -S ... -m ...', and things work as expected. I get a UI prompt
for my GnuPG password and the work flows as usual.
When I work remotely on the same workstation over SSH I have to forgo
commit signing because:
$ git commit -S log.h -m "Remove unneeded header"
error: gpg failed to sign the data
fatal: failed to write commit object
I'm using a "standard" configuration for SSH, Git and GnuPG. I am not
aware of any special configurations for this setup. However, the repo is
located on my local LAN (and not GitHub, GitLab, etc):
$ cat .git/config
[core]
repositoryformatversion = 0
filemode = true
bare = false
logallrefupdates = true
[remote "origin"]
url = ssh://git@callmaster:/var/callboot-src
fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
remote = origin
merge = refs/heads/master
There is no specialized GnuPG conf file in $HOME/.gnupg:
$ ls -A ~/.gnupg/
3F537D88ADBC1677-private-key.asc pubring.kbx
private-keys-v1.d trustdb.gpg
Here is pinentry on the machine:
$ ls -Al /usr/bin/pinentry-*
-rwxr-xr-x 1 root root 63992 Feb 5 2018 /usr/bin/pinentry-curses
-rwxr-xr-x 1 root root 72184 Feb 5 2018 /usr/bin/pinentry-gnome3
lrwxrwxrwx 1 root root 30 Sep 2 19:14 /usr/bin/pinentry-x11 ->
/etc/alternatives/pinentry-x11
And then:
$ ls -Al /etc/alternatives/pinentry-*
lrwxrwxrwx 1 root root 24 Sep 2 19:14 /etc/alternatives/pinentry-x11 ->
/usr/bin/pinentry-gnome3
lrwxrwxrwx 1 root root 40 Sep 2 19:14 /etc/alternatives/pinentry-x11.1.gz
-> /usr/share/man/man1/pinentry-gnome3.1.gz
My .bashrc includes:
export GPG_TTY=$(tty)
Search is finding a lot about Git signing failures, but not results for
this particular situation. I have to turn the problem over to the
maintainers since I can't figure it out.
What users like me expect is, things just work regardless of how we are
logged in.
