Contents in bin folder delete itself during core updates

I have a strange behavior with the bin folder. The contents inside of it deletes itself during a core update. The update will fail during the process. Accessing the website during this time says update in progress. Try again later. Inside the bin folder which contains 4 files are gone. Upgrading the plugin via cli is ok. Using the admin to upgrade the core is fine.

duc@nginx:/var/www/httpd/jcb/bin$ ls
composer.phar gpm grav plugin

Under tools -> reports in admin shows no errors and green all across. Admin page and website runs fine.

Can you clarify? At first you say files get deleted, but later you say updating both via CLI and admin are fine 🤔

Sorry for the confusion.

Basically, when I update via CLI, the files inside the bin folders gets deleted during the process. Thus, the update failed.

However, if I update the core by logging into the admin gui, it updates just fine.

This is the error during the update:

duc@nginx:/var/www/httpd/jcb$ sudo bin/gpm selfupgrade -f
