I've used Dell Repository Manager successfully many times, but recently the bootable ISOs it creates have started failing on my PowerEdge R640 servers. The problem occurs with DRM 3.5.0 and 3.5.1 on a Windows 11 client, with current catalogs and plugins, while the servers are running BIOS 2.28.1.
I create the image by selecting the "Platform Bootable ISO" option, choosing the R640 platform, selecting an output location, and allowing the job to complete. The ISO boots successfully when mounted through iDRAC virtual media or written to a USB drive. It starts the SUSE Linux environment and begins attempting to install the firmware packages, but every package fails with errors such as:
"Trying to Upgrade DSU"
"Failed to create Support Directory"
"Package execution requires 'root' user privileges."
The process eventually hangs after several packages fail. Since the ISO is supposed to automate the update process, there is no obvious way to intervene and elevate privileges manually. Has anyone found a reliable fix or workaround for this bootable ISO issue?

I’ve run into the same behavior with DRM 3.5.1.89 while building an image for a PowerEdge R550. A lot of the bootable images created by the tool seem unreliable—some fail outright and others take far longer than expected. Trying an older DRM installer may be worth testing, although using a previously released firmware ISO was the only practical workaround I found.
I reproduced this with the current DRM release on both Windows and Linux. Rolling back to DRM 3.5.0 doesn’t resolve it, so the problem appears to be in the bootable ISO plugin rather than the main Repository Manager application.
