Unable to update my system

After I go with sudo pacman -Syu

I get :: Replace hwids with core/hwdata? [Y/n] y

I click Y, the default option and get:

error: unresolvable package conflicts detected
error: failed to prepare transaction (conflicting dependencies)
:: tlp and power-profiles-daemon are in conflict



Pretty much you need to remove TLP from your system because its replaced by power-profiles-daemon.

I used this command in terminal to remove the unneeded dependencies:

sudo pacman -Rs tlp

Ok, did that and it went along. Bu the it stopped again with:
error: libspeechd: signature from “Alexander Epaneshnikov email@alex19ep.me” is unknown trust

File /var/cache/pacman/pkg/libspeechd-0.11.1-1-x86_64.pkg.tar.zst is corrupted (invalid or corrupted package (PGP signature)).
Do you want to delete it? [Y/n]
If I click yes, it closes without updating anything

Update archlinux-keyring first, then continue with the -Syu .
