无法在Arch Linux上安装Atom Editor

Question

package re2-20170101-1 is not installing.

i have also marked extra as siglevel never because before it was giving signature error

error: re2: signature from "Anatol Pomozov <anatol.pomozov@gmail.com>" is invalid
:: File /var/cache/pacman/pkg/re2-20170101-1-x86_64.pkg.tar.xz is corrupted (invalid or corrupted package (PGP signature)).
Do you want to delete it? [Y/n] n

then i marked extra as siglevel never

[extra]
SigLevel = Never
Include = /etc/pacman.d/mirrorlist

so i get this error.(404 error was also before adding signlevel = Never)

[pi@vision pacman.d]$ sudo pacman -S atom

Answer 1

1. Pacman said, the key is corrupted:

error: re2: signature from "Anatol Pomozov " is invalid :: File /var/cache/pacman/pkg/re2-20170101-1-x86_64.pkg.tar.xz is corrupted (invalid or corrupted package (PGP signature)). Do you want to delete it? [Y/n] n

note: SigLevel = Never you should not avoid the check to staying safe.

Instead of that, You must refresh your keys list:

pacman-key --refresh-keys

If you never imported the whole archlinux keyring before, you should get it (before refresh):

pacman-key --populate archlinux

2. Finally, can see that pacman cannot find the archive. This occur often when the pkg revision has changed and outdated. (you could not see it before, cause of the PGP error)
