On a fresh install of Manjaro Sway Arm edition, I was unable to perform an update and was receiving the below error:
“error: archlinux-keyring: signature from Arch Linux ARM Build System firstname.lastname@example.org is unknown trust”
I was able to fix by:
- Opening ‘Add/Remove Applications’.
- Clicking three dots and selecting ‘Preferences’.
- Navigate for the ‘Third Party’ tab.
- Use the radio button to ‘Enable AUR support’.
- Then go back to main window, click Refresh and Apply.
