Created attachment 105022 [details] kwatchgnupg screenshot & KDE Neon User distro: Despite the fact that scdaemon is not install on my system, the selftest for scdaemon passes and Kwatchgnupg lists endlessly every 2 seconds a failing connection attempt to /usr/lib/gnupg2/scdaemon (see screenshot) That is kleopatra fails is expected because the scdaemon is not installed: # LC_ALL=C ll /usr/lib/gnupg2/scdaemon ls: cannot access '/usr/lib/gnupg2/scdaemon': No such file or directory # LC_ALL=C dpkg -l scdaemon dpkg-query: no packages found matching scdaemon # LC_ALL=C apt search scdaemon Sorting... Done Full Text Search... Done scdaemon/xenial 2.1.11-6ubuntu2 amd64 GNU privacy guard - smart card support Expected Result: 1) scdaemon selftest fails and kleopatra 2) should not retrying again and again every two seconds to connect to connect to scdaemon, but display an error msg or error notification P.S. FWIW: would be useful if the text in kwhatchgnupg could be selected for cut & paste instead of save as, kate, select, cut&pase a text fragment into the bug report
I have no smart card reader. Installing scdaemon results in 'ERR 100663404 Kartenfehler' (en: card error) every 2 seconds. IMHO that's a bug: ... 6 - 2017-04-14 14:49:18 gpg-agent[3001]: Handhabungsroutine 0x7f7e79ffb700 für fd 4 gestartet 6 - 2017-04-14 14:49:18 gpg-agent[3001]: DBG: chan_4 -> OK Pleased to meet you, process 14961 6 - 2017-04-14 14:49:18 gpg-agent[3001]: DBG: chan_4 <- OPTION display=:0 6 - 2017-04-14 14:49:18 gpg-agent[3001]: DBG: chan_4 -> OK 6 - 2017-04-14 14:49:18 gpg-agent[3001]: DBG: chan_4 <- OPTION ttyname=/dev/pts/6 6 - 2017-04-14 14:49:18 gpg-agent[3001]: DBG: chan_4 -> OK 6 - 2017-04-14 14:49:18 gpg-agent[3001]: DBG: chan_4 <- OPTION ttytype=xterm-256color 6 - 2017-04-14 14:49:18 gpg-agent[3001]: DBG: chan_4 -> OK 6 - 2017-04-14 14:49:18 gpg-agent[3001]: DBG: chan_4 <- SCD SERIALNO 6 - 2017-04-14 14:49:18 gpg-agent[3001]: new connection to SCdaemon established (reusing) 6 - 2017-04-14 14:49:18 gpg-agent[3001]: DBG: chan_36 -> SERIALNO 6 - 2017-04-14 14:49:18 gpg-agent[3001]: DBG: chan_36 <- ERR 100663404 Kartenfehler <SCD> 6 - 2017-04-14 14:49:18 gpg-agent[3001]: DBG: chan_4 -> ERR 100663404 Kartenfehler <SCD> 6 - 2017-04-14 14:49:18 gpg-agent[3001]: DBG: chan_4 <- BYE 6 - 2017-04-14 14:49:18 gpg-agent[3001]: DBG: chan_4 -> OK closing connection 6 - 2017-04-14 14:49:18 gpg-agent[3001]: DBG: chan_36 -> RESTART 6 - 2017-04-14 14:49:18 gpg-agent[3001]: DBG: chan_36 <- OK 6 - 2017-04-14 14:49:18 gpg-agent[3001]: Handhabungsroutine 0x7f7e79ffb700 für den fd 4 beendet ... Expected (at least by me) display an error notification once and stop retrying. Avoiding needless CPU cycles and 'flooding' the log output.
Re 1) The selftest is for scdaemon configuration (gpgconf --check-options scdaemon ) and not scdaemon installation. Kleopatra's selftests check that Kleopatra minmally works. It does not need scdaemon to function so there is no test for scdaemon installation. 2) Indeed Kleopatra actively polled for smartcards always. During the recent refactoring of the code to add OpenPGP Smartcard support this was fixed. It now only checks at startup or when the new "Manage Smartcard" widget is active. Sadly there is no real way to get an event from GnuPG when the Smartcard status changed. But this fixes the poll / wakeups / flooding.
