Failed to check for chroot() environment: Permission denied

This happen after a resize/moving hard disk partition through gparted.
I also tried to search the web but without results.
Can somebody give me a start point for further investigation?
Thanks

Re: Failed to check for chroot() environment: Permission denied

It could be incorrect or overly restrictive mount options on your root. Try "mount | grep -E ' / | /boot | /home'" to check current mount options, or "cat /etc/fstab" to check what fstab says. Also "ls -ld / /boot /var/cache/pacman/pkg", have a look at permissions. Look for noexec, nosuid, or nodev on the root (/) filesystem?

Remount root with proper options temporarily:

sudo mount -o remount,exec,suid,dev /

Edit fstab:

sudo nano /etc/fstab

Make sure the root line looks like this (adjust UUID or PARTUUID):

UUID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx / ext4 defaults 0 1

Remove any noexec, nosuid, nodev from the root / line, but for /boot or EFI partition, defaults or noatime is usually fine. I use noatime myself. Less "junk" imho. Example for root: defaults,noatime (no noexec etc.).

I use BTRFS though, so mine looks like:

<idiiii>    /    btrfs        defaults,rw,noatime,compress=zstd:3,ssd,space_cache=v2    0 0

Test fstab and see: "sudo mount -a"

Re: Failed to check for chroot() environment: Permission denied

This happen after a resize/moving hard disk partition through gparted.

What partitions exactly?
I assume there's also a parallel windows installation?

lsblk -f
sudo fdisk -l /dev/sda
df -h
sudo LC_ALL=C pacman -Qkk | grep -v ', 0 altered files' | grep -v backup

Re: Failed to check for chroot() environment: Permission denied

Doesn't look horribly broken
So let's see what this

Hi, on my archlinux fully update pc when i run pacman -Syu i get a lot of

actually is resp. where it's coming from.

sudo pacman -Syu --debug | tee /tmp/pacman.out
cat /tmp/pacman.out | curl -s -H "Accept: application/json, */*" --upload-file - 'https://paste.c-net.org/'

Re: Failed to check for chroot() environment: Permission denied

Seems this is coming from the systemd hooks, does

sudo systemctl daemon-reload

cause this?

stat: cannot statx '/proc/1/root': Permesso negato

https://bbs.archlinux.org/viewtopic.php … 1#p1981431 ?
What is the context here?
