Suddenly drush no longer works on Drupal 8 sites in Ubuntu

[ghost]

Just ran sudo drush --no-backup up -y as I always do sometimes for this site, but suddenly I get:

PHP Fatal error:  Method Drupal\Core\StringTranslation\TranslatableMarkup::__toString() must not throw an exception, caught Error: Class 'Drupal\locale\TranslationString' not found in phar:///usr/local/bin/drush/includes/output.inc on line 0
PHP Fatal error:  Method Drupal\Core\StringTranslation\TranslatableMarkup::__toString() must not throw an exception, caught Error: Class 'Drupal\locale\SourceString' not found in phar:///usr/local/bin/drush/includes/output.inc on line 0

Moreover, all non-dir inodes on the root goes to a new direcotry "drupal 8.2.4" and the update fails.

Any advice please?

[drzraf]

can reproduce here with drush 8.1.8, runing drush up from 8.2.3 to 8.2.6

$ drush -vd @d8.vi up drupal
[...]
rename xxx srv/www/d8/drupal-8.2.6/xxx  (for every file/dir)
[...]
Calling chdir(/srv/www/d8/drupal-8.2.6)
[...]
Executing: git fetch  ; git checkout  8.2.6
[...]
 error: Your local changes to the following files would be overwritten by checkout:
[...]
Updating project drupal failed. Attempting to roll back to previously installed version.
[...]
rename(/srv/www/d8/drupal-8.2.6/xxx, /srv/www/d8/.xxx
[...]

Using debug, files are restored. Without debug, restoration does not seem to work.
Using git reset --hard before updating seems made it work.
(Project drupal was updated successfully. Installed version is now 8.2.6)

Having the same issue, updating from drupal 8.3.0 to drupal 8.3.4 with drush 8.1.12. It is working indeed with the debug flag on (cannot understand why). This is the error message in my case:

Update information last refreshed: 28 jun 2017 17:10
 Name    Installed Version  Proposed version  Message

Code updates will be made to drupal core.
WARNING:  Updating core will discard any modifications made to Drupal core files, most noteworthy among these are .htaccess and robots.txt.  If you have made any modifications to these files, please back them up before updating so that you can re-create your modifications in the updated version of the file.
Note: Updating core can potentially break your site. It is NOT recommended to update production sites without prior testing.

Do you really want to continue? (y/n): y

I have similar problem. with this
Drupal 8.2.8 8.5.3 SECURITY UPDATE available

But "drush up" works fine in others servers with exactly same drupal and the same drush version. The problem is perhaps php modules

[drzraf]

It's probably related to hostname determination (uri inside drushrc, SERVER_NAME, $base_url and cache.

My last workaround:
In settings.php:
if (function_exists('drush_main')) { $conf['cache'] = 0; }
