gpg-agent refuse to start

[Roy Christian (DAIT-SITL)]

Hello,

Our applications called the GNUPG 1.4.2 executable and it worked without issue. We upgraded to GNUPG version 2.2.27 and now we have problems with the gpg-agent. This sometimes refuses to start. The log looks like this:

gpg-connect-agent: pas d'instance de gpg-agent en cours d'ex,cution -ÿd,marrage de ®ÿC:\Program Files (x86)\GnuPG\bin\gpg-agent.exeÿ¯
gpg-connect-agent: waiting for the agent to come up ... (5s)
gpg-agent[3580]: Attention : « --use-standard-socket » est une option obsolète - non prise en compte

gpg-connect-agent: can't connect to the agent: chec de l'appel IPC connect

- We are on Windows Server 2016 with gpg4win 3.1.15.
- We have seventeen directories (homedir) each containing the keys of a communication partner. So there can be up to 17 agents running.
- For now, after each restart of the server, I do a manual start of the seventeen agents. The starting problem is also present in manual. I use this command:
"C:\Program Files (x86)\GnuPG\bin\gpg-connect-agent" --homedir C:/ProgRRQ/GnuPG/RRQGnuPG01E /bye

- I have experimented with version 2.3.7 and the problem occurs much less often, but it is still present.
- Is our use of GNUPG 2 correct? Should we go back to the latest version 1.4?
- Here is an example of a call by one of our applications:
"C:\Program Files (x86)\GnuPG\bin\gpg.exe" --batch --yes --display-charset utf-8 --passphrase-fd 0 --pinentry-mode loopback --verbose --ignore-mdc-error  --homedir C:\ProgRRQ\GnuPG\RRQGnuPG15P -r "RQ Prod" -o "\\siaechpcq02\depotsys\EE5\EE5N731_Temp\urh1vftx.scs" -d  "\\siaechpcq02\depotsys\EE5\EE5N731_Temp\nfbxl3yo.4nb"
