[root@cyou akkoma]# su akkoma -s $SHELL -lc "./bin/pleroma_ctl instance gen --output /etc/akkoma/config.exs --output-psql /tmp/setup_db.psql"

I made some efforts to fix the glitch：

  • input echo $AKKOMA_CONFIG_PATH and return null
  • apt-get install libssl-dev
  • check access authority of libcryto.so.1.1

Anyone know what I’m doing wrong? Please let me know if I need to add any information

with love,

You probably used the wrong flavour.

# Set the flavour environment variable to the string you got in Detecting flavour section.
# For example if the flavour is `amd64` the command will be
export FLAVOUR="amd64"

In your case the flavour is amd64-ubuntu-jammy. You’re not the first to have this problem, there’s already a PR to make this more clear.

YEAH it’s the mistake I have done, I fixed flavour environment variable then my instance run. Thank you soooo much!!
