Install app-crypt/gnupg-2.2.4-r2, which pulls in app-crypt/pinentry-1.0.0-r2. With a fresh ~/.gnupg, start a new gpg-agent with --daemon. Try to create a new key with gpg --gen-key (name and email are irrelevant). Use a simple passphrase, "accept" at the weak passphrase warning, and then deliberately typo the passphrase. pinentry-curses bails and GPG aborts with EOF. I noticed this when I was sending an encrypted message and I typo'd my passphrase. The above example is a clean way to demonstrate the issue. When I launch gpg-agent with "debug 1024" and "debug-pinentry" I get this out of the log: gpg-agent[7165]: DBG: chan_11 -> SETPROMPT Passphrase: gpg-agent[7165]: DBG: chan_11 <- OK gpg-agent[7165]: DBG: chan_11 -> [[Confidential data not shown]] gpg-agent[7165]: DBG: chan_11 <- [[Confidential data not shown]] gpg-agent[7165]: DBG: chan_11 <- [[Confidential data not shown]] gpg-agent[7165]: DBG: chan_11 -> SETERROR Bad Passphrase (try 2 of 3) gpg-agent[7165]: DBG: chan_11 <- OK gpg-agent[7165]: DBG: chan_11 -> [[Confidential data not shown]] gpg-agent[7165]: DBG: chan_11 <- [eof] gpg-agent[7165]: DBG: error calling pinentry: End of file <GPG Agent> Happy to help troubleshoot further, but I'm a bit out of my depth. strace wasn't particularly revealing. I think the problem lies with pinentry, but I'm not sure where specifically. Any help is very much appreciated!

If pinentry SIGSEGVs , can you try to produce a backtrace using a core dump and gdb? (see ulimit -c unlimited and man gdb, mainly you start it up and do a "bt") To try pinentry directly, use e.g /usr/bin/pinentry <<<GETPIN That should hopefully help debugging without going through agent .. And to have it said, use a test password and not real one...
