Hi -
git pull from the GCC and Glibc repos is failing for me with the error
below. It worked fine last week and I haven't made any changes to my
ssh keys.
And are you logging in from the same workstation with access to the same
set of ssh private keys?
Is this a transient glitch or has something changed recently that I
need to make some adjustments for?
I know of nothing relevant that has changed on the sourceware side.
sign_and_send_pubkey: signing failed: agent refused operation
mse...@gcc.gnu.org: Permission denied (publickey).
fatal: Could not read from remote repository.
The usual advice is to run % ssh -vv gcc.gnu.org alive
and report the ssh level error.
"agent refused operation" sounds like a problem on the client end.
Yes, it is. "agent" refers to the ssh-agent program.
Martin, what does 'ssh-add -l' show?
Is there only one ssh-agent process shown by 'ps -ef | fgrep
[s]sh-agent'? Does its PID match $SSH_AGENT_PID?
Another possible cause is that the file permissions are not strict
enough on the private key, or on the ~/.ssh directory that contains
it. Key files should be 600 and ~/.ssh should be 700.
We solved the problem over IRC last night so just to close the loop
on it here: it turned out to be caused by Gnome keyring setting
SSH_AUTH_SOCK=/run/user/1000/keyring/ssh. With the environment
variable undefined I get prompted for the password as expected.
Thank you both again for your help in getting to the bottom of it!
Martin
