[Bug 2057885] Re: gpg return 'No dirmngr' error when handling add_extra_ppas phase

[Laider Lai]

Hi Paul,

After a long experiment, we found the key point to reproduce this issue (100%).
The key point is the number of characters of the full path for "<working directory>/work/chroot/tmp/ubuntu-image-gpg/<pubring.kbx | trustdb.gpg"

If the total number of characters >= 100, the issue is reproduced.
Ex. /home/ubuntu/workspace/iot-murcia-classic-2204/iot-image-builds/work/chroot/tmp/ubuntu-image-gpg/pubring.kbx

If the path is shorter than 100 characters, the issue is gone.
Ex. /home/ubuntu/iot-image-builds/work/chroot/tmp/ubuntu-image-gpg

Looks like there is a string array declared with 100 length.
Could you try to reproduce this issue on your side and check the root cause? Tks.
