Bug 3941

the attached log file does not include a connection attempt so is of "limited use".

Have you tried using STARTTLS instead?

Created attachment 1832 [details]
LOG-2 file [claws-mail --debug]

@Paul
I did not exclude any login items.
I'm adding a new log. I used "claws-mail --debug" option.

@Michael Rasmussen
Yes. I also tried this before reporting the bug. Setting STARTTLS does not help.

what is the output of these 2 commands?:

$ libetpan-config --libs
$ libetpan-config --version

Thank you very much for your interest in my problem!

Zypper shows that I have libetpan17 (1.6-1.11), but the effect of using the commands indicated by you is empty:

name@hostname:~> libetpan-config --libs
bash: /usr/bin/libetpan-config: No such file or directory
name@hostname:~> libetpan-config --version
bash: /usr/bin/libetpan-config: No such file or directory

name@hostname:~> sudo libetpan-config --libs
sudo: libetpan-config: command not found
name@hostname:~> sudo libetpan-config --version
sudo: libetpan-config: command not found

I decided to additionally install libetpan-devel (1.6-1.11) (and two dependencies: cyrus-sasl-devel and libdb-4_8-devel):

Installing cyrus-sasl-devel-2.1.26-16.1.x86_64.rpm (installed size 1,25 MiB)
Installing libdb-4_8-devel-4.8.30-33.1.x86_64.rpm (installed size 154,1 KiB)
Installing libetpan-devel-1.6-1.11.x86_64.rpm (installed size 1,13 MiB)

The effect of using commands you specify is as follows:

name@hostname:~> libetpan-config --libs
-L/usr/lib64 -letpan -lz -ldb-4.8 -lz -pthread -lsasl2

name@hostname:~> libetpan-config --version
1.6

I tried to run claws-mail. The error still occurs. No changes.

That looks suspect. Here is the output on my system:

$ libetpan-config --libs
-L/usr/lib64 -letpan -lcurl -lexpat -lz -lgnutls -lgcrypt -lgpg-error -lz -ldb-5.3 -lz -llockfile -pthread -lsasl2

It looks like your libetpan is not compiled with gnutls support, and that would explain the failure it has in attempting the encrypted connection.

I think you're right.

I replaced the repository with claws-mail and libetpan:

from: https://download.opensuse.org/tumbleweed/repo/oss/suse/x86_64/
claws-mail-3.15.1-2.1.x86_64.rpm
libetpan17-1.6-1.11.x86_64.rpm

to: https://download.opensuse.org/repositories/server:/mail/openSUSE_Tumbleweed/x86_64/
claws-mail-3.16.0-1.2.x86_64.rpm
libetpan20-1.8-28.1.x86_64.rpm

Unfortunately, I did not find the right libetpan to substitute, which would allow full verification (without changing the claws-mail version). Claws-mail 3.15 did not work with libetpan 1.8.

Currently the problem has disappeared. Everything is working properly.

Thank you very much for help. I think that this bug reporting can be closed.

If you want to take a look at my RPMs files, in the links above you will find RPMs that I have installed (previously and now). Because of the size, the first repository loads in the web browser a bit longer. Below you will find direct links:
https://download.opensuse.org/tumbleweed/repo/oss/suse/x86_64/claws-mail-3.15.1-2.1.x86_64.rpm
https://download.opensuse.org/tumbleweed/repo/oss/suse/x86_64/libetpan17-1.6-1.11.x86_64.rpm

Problem is reproducible for me with openSUSE Tumbleweed using the default repositories.  I think we've established that this a downstream problem with the openSUSE packages.  Is there a downstream bug report?  If so, please let me know the URL.  Otherwise, I will report it myself.

No answer to my last comment, so I opened an openSUSE Tumbleweed bug myself: <https://bugzilla.novell.com/show_bug.cgi?id=1077025>

you could have been a little more specific in your suse bug report. The problem is with the libetpan package.

Fair enough; I've updated the report to mention your diagnosis.
