Roll back upgrade after downgrading not supported-message

[tflidd]

Background: https://help.nextcloud.com/t/using-updater-app-to-get-nc-10-beta-or-daily/1856

I failed to upgrade to NC daily. After the code was replaced successfully by the updater app, I could start the actual upgrade because it shows: Downgrading is not supported and is likely to cause unpredictable issues (from 9.0.53.0 to 9.0.52.0)

So I want to roll back. It would be nice if the updater-app could roll back the upgrade itself and recover the backup. So I put back the code manually from the backup created by the updater-app. Now I get a Internet server error:

{"reqId":"tjnpRTl1+jirbXKPWkOZ","remoteAddr":"2001:","app":"index","message":"Exception: {\"Exception\":\"OCP\\\\AutoloadNotAllowedException\",\"Message\":\"Autoload path not allowed: \\\/var\\\/www\\\/nextcloud\\\/apps\\\/theming\\\/lib\\\/template.php\",\"Code\":0,\"Trace\":\"#0 \\\/var\\\/www\\\/nextcloud\\\/lib\\\/autoloader.php(172): OC\\\\Autoloader->isValidPath('\\\/var\\\/www\\\/nextcl...')\\n#1 [internal function]: OC\\\\Autoloader->load('OCA\\\\\\\\Theming\\\\\\\\Tem...')\\n#2 \\\/var\\\/www\\\/nextcloud\\\/lib\\\/private\\\/server.php(569): spl_autoload_call('OCA\\\\\\\\Theming\\\\\\\\Tem...')\\n#3 \\\/var\\\/www\\\/nextcloud\\\/3rdparty\\\/pimple\\\/pimple\\\/src\\\/Pimple\\\/Container.php(113): OC\\\\Server->OC\\\\{closure}(Object(OC\\\\Server))\\n#4 \\\/var\\\/www\\\/nextcloud\\\/lib\\\/private\\\/appframework\\\/utility\\\/simplecontainer.php(102): Pimple\\\\Container->offsetGet('ThemingDefaults')\\n#5 \\\/var\\\/www\\\/nextcloud\\\/lib\\\/private\\\/servercontainer.php(87): OC\\\\AppFramework\\\\Utility\\\\SimpleContainer->query('ThemingDefaults')\\n#6 \\\/var\\\/www\\\/nextcloud\\\/lib\\\/private\\\/server.php(1227): OC\\\\ServerContainer->query('ThemingDefaults')\\n#7 \\\/var\\\/www\\\/nextcloud\\\/lib\\\/private\\\/template.php(79): OC\\\\Server->getThemingDefaults()\\n#8 \\\/var\\\/www\\\/nextcloud\\\/lib\\\/base.php(308): OC_Template->__construct('', 'update.user', 'guest')\\n#9 \\\/var\\\/www\\\/nextcloud\\\/lib\\\/base.php(924): OC::checkMaintenanceMode()\\n#10 \\\/var\\\/www\\\/nextcloud\\\/index.php(39): OC::handleRequest()\\n#11 {main}\",\"File\":\"\\\/var\\\/www\\\/nextcloud\\\/lib\\\/autoloader.php\",\"Line\":152}","level":3,"time":"2016-07-24T09:10:23+00:00","method":"GET","url":"\/nextcloud\/","user":"--"}

I tried the occ-command and it told me that I'm in maintenance mode. So I turned it off and voilà it works again. That's great news, however there are a lot of confusing messages and steps on the way.

Long story short:

1. Install nextcloud 9.0.53
2. Enable updater app
3. Switch to upgrade the daily releases
4. Error with major upgrade (I suppose the version numbers are not correct->see linked topic)
5. Restore updater-app-backup manually
6. get Internal Server error
7. solve by switching maintenance mode off

Yes, the versioning seems like a real mess, updater cannot be used, happened to me exactly the same.

[pboesch]

Exactly the same for me:

$ sudo -u nextcloud php occ upgrade without error.

And now on the webui:

Downgrading is not supported and is likely to cause unpredictable issues (from 9.1.2.2 to 9.1.1.5)

@pboesch Could you post your updater.log (inside the data directory)? And sorry for the late response I was sadly busy with other stuff :(

A rollback feature for the core and the apps would be useful indeed. Maybe this convenient WordPress plugin helps as a role model: https://wordpress.org/plugins/wp-rollback.
