30. Host realize systemd-networkd fail.
31. journalctl don't work.
32. journalctl works for host
33. Host realize that the binary have "Permission denied"
34. Host realize someone had the same issue in september 2020 on reddit. Systemd's fault, only solution is reinstall. (https://reddit.com/r/linuxquestions/comments/iyk0bp/boot_permission_denied_issue/)
35. Buy another VM and attach the old disk to it.

42. Copy postgresql files from old disk to new
43. Reboot systemd service. It works.
44. Copy forgejo files from old disk to new
45. Reboot systemd service. It works
46. Can't connect to librejo through web browser...
47. use curl over ssh. Works fine in local
48. Use IP directly. Works fine (not really since openssl will not accept an https over ip)
49. Search why the domain don't work.

51. Lost 10 minutes of my life.
52. Realize its browser fault. Restart web browser
