php7.2-sodium: module "sodium" already loaded

[luispabon]

Looks like sodium is already compiled into PHP core:

root@a34b2c6dffe0:~# php -i|grep sodium
sodium
sodium support => enabled
libsodium headers version => 1.0.14
libsodium library version => 1.0.14

But then, php7.2-sodium is also available, and when installed it tries to load twice, hence the warning. I'd suggest to get rid of that package entirely.

Not sure if it's related, but I'm getting

$ php -v
php: symbol lookup error: php: undefined symbol: sodium_pad

after installing PHP7.2 from the PPA. Whether php7.2-libsodium is installed it doesn't seem to matter for me.

What's output of:
apt-cache policy php7.2
and
apt-cache policy php7.2-sodium
and
apt-cache policy php-sodium
?

[luispabon]

Just deleting these as I've realised 7.2 is out. Going to update the base container and report back.

[oerdnj]

@cjunge Purge your /usr/local and no, it's not related.

Apologies for the delay:

You can try this yourself on this docker image: phpdockerio/php72-cli:dodgy-sodium

Example:
docker run -it --rm phpdockerio/php72-cli:dodgy-sodium php --version

It does appear Sodium is compiled in, so fix seems to be just avoid...

apt-get install php7.2-sodium

Likely this does require fixing. Either removing Sodium from core or retiring the php7.2-sodium package.

[oerdnj]

Ah, I see. I have removed php7.2-sodium package as it is not needed anymore. It was just an leftover.

Great stuff, thank you 👍
