After 30 minutes of turn on the pc some extra application installed by me doesn't launch when I need them. The defaults installed applications works fines.

• cant launch applications

I have to reboot the system to fix the problems but after 30 minutes more and less the pc get again the problem.

How can we check SSD problems? How can we know the problems? How can we fix that? Thanks in advanced.

This script will unmount then remount the var mount point as read-write.

sudo umount /var
sudo mount -o remount,rw /var

Don't know if the problem is about btrfs, the problems was persisting, the problem avoid me to work with the computer normally. I had reinstalled kubuntu 21.04 in the root partition now with ext4 file format. I tryed to install kde neon but it doesn't recognize the existed /efi/boot partition there and always showed me the message "the system need a efi/boot partition with a fat32 file system, create one"

At today the problem was fixed, but if anyone have had the same problem and know about what would be the origin of the problem feel free to write any insights.

the command sudo smartctl -t short -a /dev/sda say that my SSD has a SSD_Life_left of 004, this does worry.

chris@k21:~/Documents/web/logindo$ sudo smartctl -t short -a /dev/sda |grep SSD_Life_Left
