Hi guys,

I have reinstalled my Seafile server on Ubuntu 22.04 and after the command “docker-compose up -d” I get the following error:

Meanwhile nearly a year later… Here is the solution… @Borotes

Examine your docker-compose.yml file, I suspect your DB password has the sequence iYNe… I’m also guessing that the preceding character for the sequence is either $ or !.. for example.

…$iYNe…
…!iYNe…

Remove/replace that character from the password string (it should appear at least twice in your YML file).

Done! I suffered the similar problem.
