Problem upgrading from 2.2.6 to 2.2.7

[denialdesign]

I'm trying to upgrade 2.2.6

When I run the web setup wizard I get this response.

Check Component Dependency

We found conflicting component dependencies.

Command "update" failed: Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

Problem 1
- magento/product-community-edition 2.2.7 requires composer/composer 1.4.1 -> satisfiable by composer/composer[1.4.1].
- magento/product-community-edition 2.2.7 requires composer/composer 1.4.1 -> satisfiable by composer/composer[1.4.1].
- Conclusion: don't install composer/composer 1.4.1
- Installation request for magento/product-community-edition 2.2.7 -> satisfiable by magento/product-community-edition[2.2.7].

When I try the command line upgrade I just get memory errors.

My composer version is 1.6.4 so newer than 1.4.1

The site is on shared hosting so I can't downgrade or upgrade composer.

My composer.json file contains:

Hi @denialdesign

Have you tried by running composer update command ?

From the command line SSH terminal run composer update command first and then try to upgrade your Magento version and let us know if its works or not !

Note : if you are not able to update using wizard then you required command line access for sure - to upgrade/downgrade the version of composer.

Hope it helps !

When I try the command line upgrade (composer update) I just get memory errors.

Hi @denialdesign

then i would suggest you to contact your hosting team and ask them to increase your memory limits.

so you will able to upgrade for the same !

[denialdesign]

The memory is already set to maximum, 8GB, and I'm still getting memory errors due to forkbomb protection which the hosts won't disable.

When I try to update to 2.2.6 to 2.3 I get this error.

How can I resolve this?

"magento/product-community-edition 2.3.0 requires magento/zendframework1 ~1.14.1 -> satisfiable by magento/zendframework1[1.14.1]."
