Update to 3.6.3: hitting php memory limit

Question

I'm trying to update my installed Joomla! 3.6.2 to 3.6.3 using the update tool provided. On doing so I seem to hit the php Memory limit:

Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 8912897 bytes) in /$PATH/www/libraries/joomla/utilities/buffer.php on line 104

I'm hosting on a shared hoster (all-inkl.com) and tried to increase Memory limit by putting ini_set('memory_limit','256M'); into my index.php an /administrator/index.php. Both did not seem to change anything.

I tried updating as described in the joomla doc but Install from URL and Upload a Package also run into the memory limit. The Install from directory method complains that "Path leeds to invalid packet" ("Der Pfad führt zu keinem gültigen Paket!") and "Warning: Joomla! Packet cannot be installed like an extension, please use update component." ("Das Joomla!-Paket kann nicht wie andere Erweiterungen installiert werden. Hierfür muss die Joomla!-Aktualisierungskomponente genutzt werden.")

Which other updating option do I have?

Answer 1

Regarding the issue: "Fatal error: Allowed memory size of" you can ask your hosting to increase these values from the php.ini :

max_execution_time = 30
max_input_time = 60
memory_limit = 128M

Check this manual. altough it says update to 3.5 but you can choose any method in that document to update to 3.6.3

Method C worked for me.
