SOLVED Pacman error inside of container

lenhuppe · 2019-05-19 01:11:16

I am learning LXD and trying to install the pacman group base-devel inside of a container. The install fails when it reaches the file-5.36-1 package. The strange thing is that I can install the same package onto the localhost just file.

Here is what I am seeing:

lxc exec test -- pacman -S file

warning: file-5.36-1 is up to date -- reinstalling

looking for conflicting packages...

Packages (1) file-5.36-1

warning: failed to retrieve some files
error: failed to commit transaction (invalid url for server)
Errors occurred, no packages were upgraded.

When I query the container it says that the package is already installed:

lxc exec test -- pacman -Q file

file 5.36-1

From the localhost I have no issue:

sudo pacman -S file

I am no expert on containers so I am not sure where to be looking for clues. I can't tell if this is a procedural error, a permissions issue or a bug.

Any ideas for how to go about troubleshooting this one?

Do you get this every time, or did this message only appear once?

If you get that message repeatedly, I suspect that's related - something is deleting (at least) the /var/cache/pacman/pkg directory.

I don't get the warning every time. I can install other packages just fine. Not sure how that came about. I may have done something wrong.

Meanwhile I have found the issue. The current version of "file" is 5.37-1 and the version that base-devel is attempting to install is 5.36-1. That's why I get a 404 error.

My guess is that the base-devel group needs to be updated accordingly but I am not sure if I can do that on my end.

No, package versions cannot be in a group - just the package is. The problem is then that you database needs to be refreshed (-y):

lxc exec test -- pacman -Syu file

That did it.
