Problem refreshing keys on Linux

[Hölzel]

Hello,

recently, interacting with the keyserver 'hkps.pool.sks-keyservers.net' is apparently broken on GnuPG 2.2.9-1 on Arch Linux 4.17.8-1.
Please find attached the ouput of 'env LANG=en_US.UTF-8 gpg -vvv --debug-all --search-keys Torvalds'.

The output of 'gpg-connect-agent --dirmngr 'KS_GET 0x4D1E900E14C1CC04' /bye' is as follows:
ERR 167805009 No such file or directory <Dirmngr>

This issue might be similar to: https://lists.gnupg.org/pipermail/gnupg-users/2018-June/060663.html

Any help is appreciated.

Sincerely
Julian
