How to show details of error in Alpine apk

Question

I use Alpine Linux 3.9.3 x86_64

when I issue:

# apk upgrade

the output is:

3 errors; 1973 MiB in 519 packages

How can I get the details about those 3 errors? I tried the --verbose flag but result is same.

These are the workarounds I thought would work:

apk -sv fix

-s (or --simulate) should simulate the fix without doing it and -v (or --verbose) should show more details but neither is working.

The result is:

# apk -sv fix
(1/3) Reinstalling fuse-common (3.2.6-r1)
(2/3) Reinstalling fuse-openrc (3.2.6-r1)
(3/3) Reinstalling xorgproto (2018.4-r0)
3 errors; 524 packages, 2845 dirs, 48016 files, 2002 MiB

But still no details, just a short summary. I wish to know what's wrong and I can't find any logs or something like that.

Solution 1

apk fix

This command lists and fixes the errors.

Solution 2

I have run into the same issues and tried to read the source code in order to find out the way of displaying error details. Unfortunately, I think there is no way by apk CLI.

But...

In src/commit.c#L357-L374, It seems like the numeric errors in the output is stored in variable errors. For example, 3 errors; 1973 MiB in 519 packages.

    if (errors)
        snprintf(buf, sizeof(buf), "%d error%s;", errors,
             errors > 1 ? "s" : "");
    else
        strcpy(buf, "OK:");
    if (apk_verbosity > 1) {
        apk_message("%s %d packages, %d dirs, %d files, %zu MiB",
                buf,
                db->installed.stats.packages,
                db->installed.stats.dirs,
                db->installed.stats.files,
                db->installed.stats.bytes / (1024 * 1024));
    } else {
        apk_message("%s %zu MiB in %d packages",
                buf,
                db->installed.stats.bytes / (1024 * 1024),
                db->installed.stats.packages);
    }

In src/commit.c#L326-L342, The errors is increased when broken_files or broken_scripts of ipkg (which refer to installed package) is evaluated to true. So there is a change for us to distinguish that.

    r = change->old_pkg &&
        (change->old_pkg->ipkg->broken_files ||
         change->old_pkg->ipkg->broken_script);
    if (print_change(db, change, prog.done.changes, prog.total.changes)) {
        prog.pkg = change->new_pkg;
        progress_cb(&prog, 0);

        if (!(apk_flags & APK_SIMULATE) &&
            ((change->old_pkg != change->new_pkg) ||
             (change->reinstall && pkg_available(db, change->new_pkg)))) {
            r = apk_db_install_pkg(db, change->old_pkg, change->new_pkg,
                           progress_cb, &prog) != 0;
        }
        if (r == 0 && change->new_pkg && change->new_pkg->ipkg)
            change->new_pkg->ipkg->repository_tag = change->new_repository_tag;
    }
    errors += r;

After reading code in src/database.c#L874-L885, it shows there is a database file which stores information of installed packages, and it has an undocumented character field f which indicates the error type that we would like to know.

    case 'f':
        for (r = 0; r < l.len; r++) {
            switch (l.ptr[r]) {
            case 'f': ipkg->broken_files = 1; break;
            case 's': ipkg->broken_script = 1; break;
            case 'x': ipkg->broken_xattr = 1; break;
            default:
                if (!(apk_force & APK_FORCE_OLD_APK))
                    goto old_apk_tools;
            }
        }
        break;

Proof of Concept

The package fontconfig and gdk-pixbuf both have a broken script (f:s).

Well, I'm afraid this is not what I'm asking about. The solution you have provided will do the fix when I'd asked about getting details of those errors.
