Hi Michael,

I have adjusted my sudo command to only wait for 1 minute before timing out but I have not reproduced getting the authentication request by just running the mount command.

I checked with lsblk and loop is present but it is not mounted to anything.

I then reran the mount command without strace and it cam back with

mount: /mnt/: /tmp/test.img is already mounted.

I then saw that in my graphical file manager IPFIRE_EFI was shown in the list of devices. t is shown as available for mounting and opening. If I click on that device then I get the authentication box showing up asking for my password. It looked like previously it tried to auto mount it and hence asked for the authentication but now it doesn't do that but the mount command thinks it is mounted.

Hopefully the strace I provided gives enough info. If not then just let me know what else I need to run, test and provide.

Regards,

Adolf.
