Upgrading Drupal

Hi guys, I am new to Drupal and just looking for some tips getting my dev environment going.

So I have a working container with drupal, mariadb, drush etc... so after installing Drupal with the installer, I install themes and such. How do I keep that work? It seems if I drop the container I lose all my work. How could I ever work in a team then? Do I use git inside the container and pull and push from within?

Any help would be much appreciated.

After updating to Drupal 7.60, all my slideshows stopped working. Looking at the suggestions at https://www.drupal.org/project/views_slideshow/issues/2269963, I checked to see that I had the sites/all/libraries/jquery.cycle/jquery.cycle.all.js structure and file. I do. If this is not the issue, then what?

Thanks!

Hello

Is it safe to upgrade from Drupal 7.38 to 8.6.11? My website (www.lohesurf.eu) has some customized modules installed and it makes me worried, if they still work after upgrade or not.

Best regards,

Andres

I am using Acquia Dev Desktop (latest version). After having a breakdown by not able to update Drupal core yesterday, I have decided (for the second time in a month) to ditch everything and start my site from scratch (...imagine the frustration at this point...).

So I have used Acquia Dev Desktop to install a new local instance of Drupal 8.6.10. I know 8.6.11 is out, but ADD installs 8.6.10 (after all 8.6.11 is just 1 day old). Anyhow, after doing a fresh new install, there is an error in the Status Report:

I am unable to update my contrib modules using ftp. I get errors like

Update failed! See the log below for more information. Your site is still in maintenance mode.

admin_toolbar

• Error installing / updating
• File Transfer failed, reason: Cannot remove file

/modules/contrib/admin_toolbar/admin_toolbar.module

I have give 755 permission to the site folder also give apache ownership.  What else needs to be done. 

Drupal 8.6.10 

Thanks
