Alex's questions

I am trying to update the packages on my CentOS 8 server, but when I run sudo dnf update, the following message shows up:

Last metadata expiration check: 0:43:34 ago on Wed 12 May 2021 11:59:25 AM CEST.

(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

There is a conflict with packages installed and packages that are available for update. How can I fix this problem so that everything updates smoothly?

I am working with CentOS 8 and I have a problem with UIDs and User Names. I have installed VestaCP to manage my websites. The user by the name of "user123" and UID 1007 is the owner of all the websites (user in VestaCP). Then I have created individual FTP users for each website. Each FTP user has the following name format: "user123_random", where random is a random text. Each FTP user has a different name, but they all share the same UID (1007) (this is the default behavior when creating new FTP users).

Now the problem happens when I am checking the ownership (user) of each website or file inside that website. So technically, the owner belongs is UID 1007. The problem here is that CentOS 8, for some reason, it is showing "user123_random" as the owner of the websites instead of "user123".

The curious thing is that when I do a "id -nu 1007", it returns the name of the last FTP user created with the prefix "user123_". So I assume, this is what CentOS 8 does internally, showing the last username (with same ID 1007) as the owner of a file/directory. This is not how CentOS 7 worked. CentOS 7 would show "user123" as the owner of the files, irrespective of adding new FTP users with the same UID.

The question is...is there a way to change this behavior in CentOS 8, so that it behaves as CentOS 7? So that the inverse name search by UID returns the "first created user" with that UID.
