Hello. I am using GNU Emacs 27.1 on Linux Mint 21. I am experiencing a problem that I did not have with my previous setup: Emacs 26.3 on Linux Mint 20.3. I have an SSH key, protected by a passphrase, that I use to connect to a remote host. As the key is in my .ssh directory with a standard name, it is automatically detected and unlocked at login by gnome-keyring-daemon. So when I ssh to the remote host from a terminal, the ssh agent provides the passphrase and I do not have to enter it.
Now here is the strange part. When I try to connect to the remote host from Emacs, Emacs may or may not ask me the passphrase. It seems to depend on how long ago I logged in. If I try the connection in Emacs immediately after login, Emacs does not ask me the passphrase, and Emacs never asks the passphrase from then on in this session. If I try the connection in Emacs for the first time in my session, say, a few hours after login, Emacs asks me the passphrase. So it seems that tramp has access to the ssh agent or not depending on how long has elapsed since login. Note that there is no such problem from the Gnome terminal. Even when Emacs asks me the passphrase, the terminal does not. The ssh agent is here (I see it in the list of processes) and the terminal has access to it. Does anybody understand this? Is there a timeout period after which gnome-keyring is not able to communicate with Emacs? And why is this different in Linux Mint 20.3 and 21? -- Regards, Lionel GUEZ Laboratoire de météorologie dynamique École normale supérieure 24 rue Lhomond, 75005 Paris
