First run screen to be expected, asking for admin-user credentials, DB-connect and Data-path
see screenshot:

unknown - shared hosting, debian 7 supposed
Web server:
unknown - shared hosting, apache2 supposed
Database:
MySQL 5.5.54-0
PHP version:
7.1.2
ownCloud version: (see ownCloud admin page)
9.1.4
Updated from an older ownCloud or fresh install:
fresh
Where did you install ownCloud from:
owncloud.org
@stkjj Only ownCloud 10.0 is supporting PHP 7.1 as stated in the message, this is absolutely correct.
Or do i missing something here and whats the reason of your report?
Works as designed.
cc @DeepDiver1975 if you want to emphasize
I'm not running 7.1.3 but 9.1.4 the error message is wrong.
I don't think it's worth spending time on this minor thing... but setting as junior job if anyone from the community wants to step up. Pretty sure the version must be read from PHP directly so not sure why PHP would report the wrong version...
The wording might be confusing. The "You're currently running 7.1.3" message refers to the PHP version not ownCloud version. @stkjj please suggest a better wording.
This should be just changing the wording, nothing else.
No, @stkjj says that his PHP version is 7.1.2, not 7.1.3. But the UI somehow detects 7.1.3.
Not sure why.
@PVince81 I don't think that this is about PHP 7.1.2 vs. 7.1.3. The code is using the PHP_VERSION constant:
https://github.com/owncloud/core/blob/v9.1.4/index.php#L39
so that version can't be wrong (probably the hoster has updated from 7.1.2 to 7.1.3 or havn't updated the text in the admin backend).
This is more about that one might assume that the following text:
You're currently running 7.1.3
refers to the ownCloud version and not the PHP version.
@stkjj Might be able to clarify.
I just try this bug with a docker image of php7.1.2 and it says:
You are currently running 7.1.2. Please use at least ownCloud 10.0.0.
Like @kdslkdsaldsal says it sound like your hosting update your php version. Could you check your installed PHP version?
Why is ownCloud server v10 not yet packaged? This should solve the problem. I created a new ticket for that: #28980.
The previous message says "PHP 7.1" so reading both lines together does connect together.
Any volunteer to adjust the message ?
I will adjust the message to say "PHP" before the version number.
