I have a little Ubuntu 22.04 cloud server.

I couldn't get it to send email, so I just save messages from the contact webpage to the server using php and download them with a bash script. I only get a few messages, it's not very active.

I usually upload or delete files using Filezilla.

In the folder

I had 3 messages from people who wanted to improve my webpage for me. I could not delete them.

Below is from Filezilla:

Why couldn't I delete them?

Trial messages from myself or friends didn't have this problem, I can delete them in Filezilla, no problem.

Was it the spaces in the file names?

I connected to my cloud server using ssh, went to the directory with the messages and used rm:
I got this message each time:

When I entered y, the file was deleted! As far as I could see, these messages had exactly the same permissions as the files I could delete.

How to do this in a better way?

First of all it looks like Filezilla not detecting that there's a CR/LF pair between the name and e-mail address.

Second, regarding permissions, it's impossible to really tell as you don't include any details of what the permissions and output from chattr for the files.

Sorry, the permissions were rw r r

I think the write bit is missing.
Try
Or set all the write bits with
Apparently there is a bug in Filezilla concerning the special characters in the file names.

Thanks, I will try that next time I have messages from those who would improve my webpage!

When I log in through ssh, I am the admin with sudo powers, so I thought I could delete anything in the webpage part of the cloud at least!

I put

--remove-source-files

in my bash script rsync command.

Maybe that will do the job!
