I am trying to get BackupPC to work on a new machine, new distro
(Fedora28) and am new to BackupPC 4 (but I am an old user with
predecessor versions of BackupPC).
The Fedora package (BackupPC 4.2.1-1.fc28) gives me (in addition to some
simple issues - inadequate file permissions, missing apache.users file -
a serious problem with the web user interface, and I would appreciate help.
I have no problem to get (requesting <server-address>::/BackupPC) a
first page correctly displayed by my browser (the GeneralInfo page). But
when, from that page, I request some action, the requested page appears
to be very shortly displayed (too short to verify correctness) and is
immediately wiped out again by a newly displayed GeneralInfo page.
To assess this interpretation of the problem and better understand what
is happening, I added debugging code that traces the calls that BackupPC
makes in responses to my request, resp. what is triggered by apache:
- the sequence of calls looks somewhat chaotic,
- there appear to be redundant initial calls to the CGI initialisation
in sbin/BackPC_admin,
- such redundant calls also happen immediately after the call in
response to my request and, in fact, result in the GeneralInfo page to
be launched again and overwrite the initially requested display.
I have no idea whether this is a problem of Fedora packaging, of
BackupPC implementation, or of my local setup (which is straightforward
Fedora28 with Xfce).
To illustrate my problem, I attach a trace printout that I get in
response to requesting (form the top-level page) the page for a specific
host (corresponding result for server calls, e.g. Status).
Did somebody already hit a problem similar to this problem? can I get
advice how to further clarify?
Thanks in advance, Juergen
