Create CT

[mikayil]

How can I fix the error I got after updating Proxmox?

TASK ERROR: unable to create CT 106 - command 'lxc-usernsexec -m u:0:100000:65536 -m g:0:100000:65536 -- tar xpf - --zstd --totals --one-file-system -p --sparse --numeric-owner --acls --xattrs '--xattrs-include=user.*' '--xattrs-include=security.capability' '--warning=no-file-ignored' '--warning=no-xattr-write' -C /var/lib/lxc/106/rootfs --skip-old-files --anchored --exclude './dev/*'' failed: exit code 2

Hi,
please share the full task log for the create task and output of pveversion -v. It sounds like there was an error during tar extracting the archive.

Please share the full task log for the CT 106 - Create task (e.g. double click in the UI). What exact command are you using?

That error message comes from ZSTD failing to extract the container template, because it is corrupted. You can try and re-download the container template. And you should check the health of the underling storage/physical disks.

what I noticed is that I can install ubuntu CT, I also deleted Debian 12 and downloaded it again, but it doesn't work with debian but with ubuntu it does

What kind of storage is this? What do you get when you compute the checksum, i.e.

sha256sum /mnt/pve/MCDC2301MCST01/template/cache/debian-12-standard_12.2-1_amd64.tar.zst

EDIT: For me it's:

root@pve8a1 ~ # sha256sum /var/lib/vz/template/cache/debian-12-standard_12.2-1_amd64.tar.zst
761b3b52ba296c3e396b79f89bdb30fed121d2353a641f84d633a87897ed6d19  /var/lib/vz/template/cache/debian-12-standard_12.2-1_amd64.tar.zst

and extraction works
