For some reason, I still see an update notification when I log in to my Piwigo admin panel, but when I open the update page it says:

“Currently running version 16.2.0. You are running the latest version of Piwigo.”

So it looks like the notification may be stuck or cached (cleaned everything)

[Forum, topic 34818] Piwigo 16.2.0 shows update to 16.4.0 on Environment page, but Updates

There is a small error in the instructions for updating via docker. The line for the database dump should be

docker exec -it piwigo-db-1 mariadb-dump -u piwigodb_user -p"piwigodb" | tee db_dump.sql

as per the mariadb man page:

•    --password[=password], -p[password]

           The password to use when connecting to the server. If you use
           the short option form (-p), you cannot have a space between
           the option and the password. If you omit the password value
           following the --password or -p option on the command line,
           mariadb-dump prompts for one.

           Specifying a password on the command line should be considered
           insecure. You can use an option file to avoid giving the
           password on the command line.

Was bashing my head against some walls before I found this :)

Updating docker image from v16.3.0 to v16.4.0 or v16.4.0a has an error in the log:

2026-05-05T14:43:11.247103495Z find: ‘/usr/local/bin/scripts/’: No such file or directory</pre>

Container startup seems to stop when this file is not found - no other entries in the log after this and site sending a 502 bad gateway error. 

reverted to v16.3.0 and working fine, no errors.

I also got 502 bad gateway after updating but being a long time Linux user but first time server owner, i rebooted the server and after that it was working. Horribly low tech solution, sorry.

Hi,

That's a different topic. Please start a new thread.
