corrupted pacman database ?I can see this kinda often is happening to users regularly often here… caused by powering off in between updating the system… or powerloss…
Backup automatic with systemd:Automated Backup In order to keep the backup up-to-date, automation of the aforementioned backup command makes sense. This can be realized with the tool pakbak-git [AUR] Pakbak is a bash script that is triggered by a Systemd service once the contents of the /var/lib/pacman/local directory have been changed. After installing Pakbak, the destination and the number of backups to be kept in rotation can be set.
sudo nano /etc/pakbak.conf
# Backup the database to this folder target_folder = /var/local/pakbak # Define how long backups should be kept keep_days = 5 # Define how many backups should be kept keep_number = 5
Note:The target directory must be created or already exist. Environment variables in the path, such as $HOME will not be processed.
test if it is workingTo test whether the bash script works as expected, you can manually initiate the execution with root privileges:
sudo sh /usr/lib/systemd/scripts/pakbakThen enable the Systemd service, which is the directory /var/lib/pacman/local automatically monitored for changes:
sudo systemctl enable pakbak.path
ConclusionNow you will have created regularly: pakbak-year-month-day-220137.tar.xz archives in the path you specified inside config file (target_folder = /var/local/pakbak) You can easely unpack and replace to /var/lib/pacman/local in case of pamac databse corruption.
