Problem in Upgrade from 12.0.2 to 12.0.3 with USER_SAML active

šŸš§ Installation

I had NC 12.0.2 installed with ā€œSSO & SAML authenicationā€ 1.3.4 active.

Using occ, I get this message
-bash-4.2$ php occ upgrade
Nextcloud or one of the apps require upgrade - only a limited number of commands are available
You may use your browser or the occ upgrade command to do the upgrade

I manually update appconfig row user_saml enabled to no.

The upgrade works successfully.

I can then access the system and upgrade the SAML app to 1.4.0 and re-enable it.

Has your instance access to the app store? If so it should have manually fetched the SAML update from https://apps.nextcloud.com/apps/user_saml

It has access.

I ran the upgrade (as attached).

Then I took a DB backup as it said that it had upgraded the DB - and I wanted a copy of this.

Then I just changed the enabled to No. The value of installed was 1.3.4. (I got this from the DB backup file.)

I then went to the site via the browser - as it had maintenance as false in the config file.

I ran the updater. This now worked and I was presented with the log-on screen.

I went on as an Admin user and looked in Apps.

This told me that there was an upgrade 1.4.0 available and that it was disabled. So I upgraded it and then enabled it both via the screen.

Thanks for this. This was the clue I needed to update the instance. Very much terrified to update my being using SQL for the first time.

I use Ubunut 17.04, PHP7.0 and PostgreSQL 9.6.
Below is how I updated my postgres instance:

# su postgres
# psql

Entered the postgesql command line

[postgresql]# \l (lists the databases)

found the one that was my nextcloud database

[postgresql]# \connect nextcloud_db_name

[postgresql]# \dt (shows all the tables - not a required command)

[postgresql]# \d oc_appconfig (shows the organization of the table - not a required command)

[postgresql]# SELECT * FROM oc_appconfig WHERE appid=ā€˜user_samlā€™ AND configkey=ā€˜enabledā€™;

This last command should show a " configvalue = yes ". If you get more than one row, something is wrong.

THIS UPDATES THE TABLE:

[postgresql]# UPDATE oc_appconfig SET configvalue=ā€˜noā€™ WHERE appid=ā€˜user_samlā€™ AND configkey=ā€˜enabledā€™;

This is as much a record for me as for anyone else when I have to do it in the future. :slight_smile:
