I have migrated a Jenkins server (+ WebSphere) from a Linux server to an EC2 (AWS; Redhat) Linux machine (installed Jenkins on the EC2, then migrated var/lib/jenkins from the source server).
When I want to build the jobs, nothing happens, except that an info field with the inscription "build scheduled" appears. I cannot find the corresponding positions in the planned builds:

What do I have to do to get the job to run or that the log file is written at all? Unfortunately, the log file is not described, so I cannot provide a more detailed error description.
In addition, no workspace exists (was not migrated). Jenkins says that this can be created by triggering a build. However, no builds start as already mentioned
Thanks in advance!
To solve the problem, I have already tried the migration again - nothing has improved. I have also allocated sufficient TEMP memory etc. to the workspace. Didn't help either. Various combinations (no user login, login as admin, etc.) have also not brought about any changes.
EDIT: The settings are also overwritten each time the system is started.
The allocated swap and TEMP memory were removed from the settings after a restart, for example. I had the same problem with the users & security settings.
I would like to share the solution I have found, perhaps someone else is also experiencing this.
The problem was that Jenkins had no write permissions. The plugins all threw an error.
After I gave Jenkins write permissions, these problems disappeared.
