Package: dirmngr
Version: 2.1.17-2
Severity: important
Hi!
since the upgrade to 2.1.17 (not sure if it's in -1 or -2), my dirmngr
is unusable. Any network operation triggers:
can't connect to 'hkps.pool.sks-keyservers.net': no IP address for host
... almost immediately, i.e. resolver-timeout seems to be ignored.
I've tried multiple combinations of the following settings in
dirmngr.conf:
* disabling "use-tor"
* enabling "standard-resolver"
* pointing "nameserver" to 127.0.0.1 (my Tor DNSPort, that only
listens on UDP 127.0.0.1:53)
* pointing "nameserver" to 8.8.8.8 (which should be the default
given I have "use-tor" enabled, but well)
* raising the value of "resolver-timeout"
… but none of them helped.
Downgrading to 2.1.16-3 fixes this problem.
The only weird thing about my system that I can think of is that my
/etc/resolv.conf points to 127.0.0.1 (where I have Tor's DNSPort
listening, that only handles A, AAAA, and PTR requests). In theory
this should not matter since with use-tor, DNS queries are done over
Tor to 8.8.8.8, if I got the manpage right. However, my limited strace
skills allow me to notice that dirmngr reads /etc/resolv.conf and then
connects to 127.0.0.1 and not to 8.8.8.8 (even if I explicitly set
"nameserver 8.8.8.8" in dirmngr.conf):

And dirmngr's debug log says:
DBG: dns: resolve_dns_name(hkps.pool.sks-keyservers.net): Success
can't connect to 'hkps.pool.sks-keyservers.net': no IP address for host
error connecting to 'https://hkps.pool.sks-keyservers.net:443': Unknown host
marking host 'hkps.pool.sks-keyservers.net' as dead
host 'hkps.pool.sks-keyservers.net' marked as dead
… which feels a tad self-contradictory.
Am I doing something wrong? Anything else I can do to debug?
