[solved] mkarchroot: permissions error for core.db.part

cfr · 2024-10-31 20:32:06

I know I must be doing something stupid because this is really pretty basic, but I just cannot see what.

I was trying to follow https://wiki.archlinux.org/title/Develo … ean_chroot, but I get a permissions error when I try to setup the chroot:

$ mkarchroot $CHROOT/root base-devel
[sudo] password for <username>:
==> Creating install root at /home/ <username>/chroot/root
==> Installing packages to /home/ <username>/chroot/root
:: Synchronizing package databases...
error: could not open file /home/ <username>/chroot/root/var/lib/pacman/sync/download-urrJCv/core.db.part: Permission denied
error: failed to setup a download payload for core.db
error: failed to synchronize all databases (failed to retrieve some files)
==> ERROR: Failed to install packages to new root
==> ERROR: Failed to install all packages

The instructions do not suggest I should be running mkarchroot with root privileges, so I'm reluctant to try that without understanding whether that is, in fact, what I should be doing.

sudo is setup non-standardly on my laptop, so privileges are escalated only for a single command. This sometimes means I get repeated requests for my password, but it has never caused something to fail.

You're $HOME is most likely 700
=> Move or bind-mount the repo into a public path, eg. /srv

Thanks! I read the news, but I did not realise it was connected. That is, I didn't realise this counted as a 'repo' and, also, the guidance seemed aimed at existing setups.
