Live-CD Build Error

[stef204]

From entrusted/ci_cd/live_cd, running the build.sh script gives this error:

Error: copying system image from manifest list: writing blob: adding layer with blob "sha256:xxxxxxxxxxxxxxa02d4eb6bb": processing tar file(potentially insufficient UIDs or GIDs available in user namespace (requested 0:42 for /etc/gshadow): Check /etc/subuid and /etc/subgid if configured locally and run "podman system migrate": lchown /etc/gshadow: invalid argument): exit status 1

+ echo 'Could not build entrusted-cli and entrusted-webserver'

Building from entrusted/ci_cd gives:

This is on branch main .
Linux x86_64

Any ideas how to debug?

Recommendation

I suggest trying the following prior the build

echo entrusted:100000:65536 | sudo tee -a /etc/subuid
echo entrusted:100000:65536 | sudo tee -a /etc/subgid

Reason

The problem is likely that when users are added to the system, some UIDs are not registered to /etc/subuid and /etc/subgid. On some Linux distributions, I believe that the above is done sometimes automatically when adding new users to the systems (some versions of Ubuntu at least and few other distributions, if I recall correctly).

Notes

I only ever build the Live CD on Ubuntu 22.04. I've tested builds under other distributions, but that was a while ago and there were probably few local configuration differences.
It's possible that I followed the recommended solution myself a while ago and forgot to add it in build scripts.

Thanks for the quick turnaround on this issue.
You're correct, I found this and have applied the fix. Rebuilding now, let's see.

[stef204]

Do I need to actually create user AND group entrusted on my box? (in addition to applying the fix above, I mean.)

[stef204]

Still showing this error when building from entrusted/ci_cd.

Must be related to podman and its configuration on my box?

[yveszoundi]

I occasionally had to run "podman system migrate" but that was when testing on Alpine. I suggest running manually podman system migrate and then restarting the build.

Also, which Linux distribution are you using?

I've built yesterday-today the Live CD and main binaries (Linux, Windows, Mac OS) from GitHub actions successfully -> Ubuntu Linux virtual machines with logic similar to the local build.

Please let me know if running podman system migrate helps.

I answered your more specific question in the other issue #67

[stef204]

Please let me know if running podman system migrate helps.

I've already run podman system migrate a few times, no changes.

Let's focus on #67 at the moment since that fails as well and it is more basic. We can come back to this issue here #65 once #67 is resolved perhaps.

Also, which Linux distribution are you using?

Archlinux x86_64

Closing this issue in favor of #79
