Error: php70w-common conflicts with php-common-5.4.16-45.el7.x86_64

Any help?

Try “php artisan key:generate” and add the generate key into the “.env” file as the “APP_KEY”.

If that doesn’t work, repeat with “php artisan key:generate --force”…

Let me know if that works for you?

I see only the .env.example file in home directory but not found any other .env files

I’m having this same issue. Started an hour ago, without any system change…

Same here. Since I have the daily updates enabled, I suspect a change was made to librenms on git that broke something.

Having the same issue. Posted my issue before realizing there was another similar post.

FYI, if you use apt-get to manage your packages, the package name is php7.0-mbstring.

After I ran apt-get install php7.0-mbstring

I was able to run ./scripts/composer_wrapper.php install --no-dev successfully and gain access to the GUI again.

I got hit with this as well, remember to run the commands as the librenms user :slight_smile: I spent some time debugging before I had the aha moment.
