GnuPG key import fails
I have freshly installed Debian 10 Buster (stable) and wanted to import the backup I made with old stable (9, Stretch). Seahorse 126.96.36.199 shows me the backup file but nothing happens when I select it and click on "import".
However, the import works instantly when I use the command line. (Afterwards I can use Seahorse to delete keys for example.)
I use an old Acer Extensa 5220 with 2 GB of RAM.
