Imposible to install UEFI into the EFI partition

[Beux Didier]

At the first installation on a partitioned disk :
1 swap
2 EFI
3 root
4 /usr/local
5 /opt
6 /home
7 /tmp

begin the installation and stop after few minutes saying that Ubuntu try to install package for Grub UEFI and failed may be the uefi security key or something like this. (I do not know why) It says also that the system will not boot and I have to send you this report.

When I open a Shell, and visit the target, I see that I haven't the right to read without sudo and when I list the content of EFI with sudo I see that I haven't the right to write inside. Only root can do it.

I see also the old files from Slackware and during the installation I asked to format all the partitions up-listed.

I'm looking for logs but it seems difficult to find them.

It's done but I just have my server Slackware dead until the solution will be returned for I can manage the EFI manualy ? Thank you for you help.

Happy new year and good luck and keep Linux on.
