Update manjaro failed

[amirh]

hey guys, I tried updating my Majaro using sudo pacman -Syyu, It took a long time so I decided to leave it for a couple of hours, and when I turned back, the upgrading was failed with such errors :
error: failed to commit transaction (unexpected error) Errors occurred, no packages were upgraded.
. when I restarted, the terminal appearance was weird and useless.I cannot upload image here to show it.
and I wanted to upgrade it once more to ensure that if something bad happened last time during the upgrade, it upgrades properly this time. but everything was upgraded.

can someone help me?

Welcome to Manjaro.

You left out the specific error messages that lead to that final one.
Those are important, copy+paste and properly format when posting.

As packages already got downloaded, the next attempt (to trigger the errors again)

sudo pacman -Syu

should be much faster.
