I downloaded the .iso file from Freedif (Germany).
Upon livebooting it from my USB (boot log: http://ix.io/4Aln) I noticed something suspicious: rebooting Firefox causes a new tab to open to a nsfw website, the installer gets messed up on the partition stage (the option to delete the entire disk disappears; when manually editing partitions you can only select the flags “boot” and “bios-grub”).
Download annother ISO and verify it to make sure it is OK.
Check the ISO file before using it:
To check the ISO file with the sha512:
sha512sum -c Endeavouros_Cassini_Nova-03-2023_R2.iso.sha512sum
To check the ISO file with gpg signature import our key and verify
