[php-maint] Bug#860337: php7.0: No transition path from php5 to php7.0 when upgrading to stretch

[Kienan]

Package: php7.0
Severity: important


Dear Maintainer,

When upgrading from jessie to stretch, there are no packages proposed for php7.0 when php5 is installed.

php7.0 and any other packages need to be installed manually afterwards. The php5 are not marked for auto-removal and php5 continues to be usable.

As php5 is not available in stretch, I would expect that the option be given to install related php7.0 packages and switch to using the new version.

I've marked this as important, but this doesn't actually stop this package from being used. I believe the severity is warranted so the upgrade to stretch is smooth for users.

Thanks,
Kienan
