Re: [arch-general] [ Pacman -Syu ] Creating temporary files..., error: command failed to execute correctly
Dear Eli, Thank you! Question regarding status of the bug has been filed!

Ah, now I remember that https://github.com/andrewgregory/pacutils/issues/32 is a thing. :) The --mode option has some issues. Perhaps try asking for a status update there?
Re: [arch-general] [ Pacman -Syu ] Creating temporary files..., error: command failed to execute correctly
Dear Eli, Thank you. I wrote a regulation expression, which extracts file name and path from the output of paccheck: $ sudo paccheck --file-properties --quiet | grep -Po "(?<=\').*(?=\')" | sudo pacrepairfile --uid --gid --mode --mtime However, somehow pacrepairfile was not working. For example, $ sudo pacrepairfile --uid --gid --mode --mtime /usr/lib/tmpfiles.d/colord.conf outputs /usr/lib/tmpfiles.d/colord.conf: set uid to 0 /usr/lib/tmpfiles.d/colord.conf: set gid to 0 warning: /usr/lib/tmpfiles.d/colord.conf: unable to set permissions (Operation not supported) /usr/lib/tmpfiles.d/colord.conf: set modification time to 111829 What happened with pacrepairfile?

Is there a way to ask paccheck to list only files that need to be fixed? For example, if I run sudo paccheck --file-properties --quiet I get list of files with package information and error information, such as screen: '/usr/lib/tmpfiles.d/screen.conf' permission mismatch (expected 644) Or maybe I need to write a regular expression to extract file name and path from such an output myself? No, paccheck does not have an option to do this. You could try submitting a feature request for it. :) You can extract everything between the '' though, which I think should handle any filenames since packaged filenames can contain spaces or single quotes but not newlines, and the paccheck output doesn't contain any more single quotes after the quoted filename.

As Ralph suspected, there are quite many files on my system that had wrong permissions or GID's. Is there a way to automatically correct all the permissions and GID's? Once more from the pacutils package, comes the "pacrepairfile" command. Given a list of files and the (separate, additive) arguments --uid --gid --mode --mtime you can reset the file to what its mtree data specified. If the file size/contents differ, you will have to do a bit of manual work yourself, or reinstall the package.

Dear Ralph,
Great! Thank you very much for the tips!

Perhaps there's been an errant recursive chmod or chgrp in the past by
root.
Is there a way to automatically correct all the permissions and GID's?
Others like Eli might know an mtree-specific way, but if there's a
common feature, like lots of files under /usr/bin that are group xianwen
instead of root, then find(1) could be used to first list what it would
change, allowing the list to be checked by eye, and then correct.
Something like
find -xdev /usr/bin -group xianwen -ls
find -xdev /usr/bin -group xianwen -exec chgrp root {} +
https://mywiki.wooledge.org/UsingFind might help if you're not familiar
with find(1). It has -user and -perm too.
Or you could try and use the output of paccheck(1) to produce a script
to execute, again after checking it by eye.
sudo -i paccheck --quiet --file-properties |
awk '
/ permission mismatch / {
print "chmod 0" substr($6, 1, length($6)-1), $2
}
'

The fix is to set owner of / as root.root. I tried the solution and it worked! I'm glad you fixed it. / not being root:root is strange. You may wish to sudo -i pacman -Qqkk to check for other odd permissions, etc., in case they too cause problems later. Note, it seems normal for some packages to cause grumbles from the above command. If a package is listed, I then do sudo -i pacman -Qkk atop to see more detail of the problem. Though unfortunately not enough detail, i.e. warning: atop: /var/log/atop/dummy_after (Permissions mismatch) doesn't tell me what they should be. One has to grovel around in the mtree file for that. $ zcat /var/lib/pacman/local/atop-*/mtree | > grep '^./var/log/atop/dummy_after ' | > fmt ./var/log/atop/dummy_after time=1549485614.0 size=0 md5digest=d41d8cd98f00b204e9800998ecf8427e sha256digest=e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855 $ This entry doesn't have a ‘mode=...’ stating the desired permissions. mtree(5) doesn't say so, but I think it defaults to 0644 for files based on the other mode-less entries in that mtree file that don't cause pacman to complain. Not every error means the file on disk must be changed, perhaps it's a packaging problem, but it can be a useful aid. pacman -S pacutils && paccheck --file-properties
Re: [arch-general] [ Pacman -Syu ] Creating temporary files..., error: command failed to execute correctly
Dear Ralph, Thank you very much for the lecture! It seems that the issue may be permissions. $ sudo /usr/bin/systemd-tmpfiles --create /run/tmpfiles.d/kmod.conf Arch returns: Detected unsafe path transition / → /dev during canonicalization of /dev.

After searching on-line, it seemed that similar problems were reported by other users of systemd. The fix is to set owner of / as root.root. I tried the solution and it worked! Running $ sudo /usr/bin/systemd-tmpfiles --create no longers gives me error message!

Dear list, When I upgrade the packages, from time to time I receive this error information: __Creating temporary files...,__ __error: command failed to execute correctly__ I checked on-line and it seems that I shall look for more error information in the log files. But I don't know where to start. Could you point me to the log files that I shall look into? Thank you.
