warning: could not get file information for .../anki.xml

archlinuxforever · 2026-03-22 08:46:59

Hi

Last full system upgrade I got this warning: "warning: could not get file information for usr/share/mime/application/anki.xml". After the full system upgrade, the file still does not exist.

Can someone help me to solve this issue?

xerxes_ · 2026-03-22 11:21:41

I got similar warning from time to time for file usr/share/mime/model/materialx.xml from package materialx when it is updated. For some reason pacman when updating this package is unable to extract/copy this file and with anki package probably is the same. Even if I manually unpack this file to desired directory it is deleted during package update. This happens every this package update. I don't see any negative impact, so I leave it without file as it is now, but if you need it then you have to manually unpack your missing file from anki package.

What does pacman-conf give you?

xerxes_ · 2026-03-22 11:45:44

For me I thing it gives nothing special, sane defaults:

DBPath = /var/lib/pacman/

My problem is missing usr/share/mime/model/materialx.xml and warning during materialx package update, but I think that with OP usr/share/mime/application/anki.xml and anki package it's the same (I don't have that one).

If you have it manually extracted, does it get deleted when you run `/usr/bin/update-mime-database /usr/share/mime`?

xerxes_ · 2026-03-22 12:01:18

OK, done that. Now I will have to wait for next materialx package update to find out if it worked.

UPDATE
I checked once more /usr/share/mime/model/ directory and materialx.xml file is gone after runing '/usr/bin/update-mime-database /usr/share/mime'.
Maybe it is not needed in my system?

Scimmia · 2026-03-22 14:50:08

So that explains why it's disappearing, but I have no idea why update-mime-database would be deleting it, or even if that's expected behavior. You'd have to look into that program and see.

seth · 2026-03-22 16:50:56

What are the contents of /usr/share/mime/model/materialx.xml ?
Might be an invalid mime description - the other files in /usr/share/mime/model/ remain?

loqs · 2026-03-22 16:57:48

/usr/share/mime/{all,application,audio,chemical,font,image,inode,message,model,multipart,text,x-content,x-epoc,video}/ are the output directories of update-mime-database that are cleaned before new files are generated. Packages are expected to place a mime data file in /usr/share/mime/packages/. https://specifications.freedesktop.org/ … #s2_layout
Edit:

$ pacman -F usr/share/mime/{all,application,audio,chemical,font,image,inode,message,model,multipart,text,x-content,x-epoc,video}/
usr/share/mime/application/ is owned by extra/anki 25.09.2-6
usr/share/mime/model/ is owned by extra/materialx 1.39.4-3

Scimmia · 2026-03-22 21:25:59

So that would be a packaging bug on both packages, as the PKGBUILD puts them there not the upstream build system. Need to be filed in Arch's gitlab .

archlinuxforever · 2026-03-26 14:51:09

This is the output in my PC:

$ pacman -F usr/share/mime/{all,application,audio,chemical,font,image,inode,message,model,multipart,text,x-content,x-epoc,video}/
usr/share/mime/model/ está contenido en extra/materialx 1.38.10-6

https://gitlab.archlinux.org/archlinux/ … 1de8a9714f

https://gitlab.archlinux.org/archlinux/ … erialx.xml doesn't fit into packages, https://gitlab.archlinux.org/archlinux/ … rk_items/2 actually suggested the correct solution.

It's worse, this got fixed forth and back

Here

$ pacman -F usr/share/mime/{all,application,audio,chemical,font,image,inode,message,model,multipart,text,x-content,x-epoc,video}/

returns nothing, but there are other xml files in subdirectories, except materialx.xml file.

But what about OPs anki.xml?

We'd need to see

pacman-conf

to work but am not inclined to build or test that (i don't even know what materialx is and never have used ninja)

If you put

into /usr/share/mime/packages/materialx.xml and run

/usr/bin/update-mime-database /usr/share/mime

, do things work and you get a fancy new /usr/share/mime/model/materialx ?

xerxes_ · 2026-03-26 22:32:54

No, this new materialx.xml after running /usr/bin/update-mime-database /usr/share/mime still disappears.

Other xml files from this subdirectory and from others don't have that <mime-info ... </mime-info> outer sections. This may be something different.

I didn't check progs from this package earlier, as it was installed as some dependency, but I check it now 2 of them: MaterialXGraphEditor (opens and works; it's some simple model editor) and MaterialXView - crashes:

seth · 2026-03-26 22:35:23

It disappears from /usr/share/mime/packages/materialx.xml ??
Or did you put it into /usr/share/mime/model/materialx.xml (where it has absolutely no business of being)

loqs · 2026-03-26 22:50:43

Perhaps also match by file contents in addition to extension which I believe is case insensitive on its second pass):

    <magic priority="80">
      <match type="string" offset="0:1024" value="&lt;materialx">
        <match type="string" offset="1:128" value="version="/>
      </match>
    </magic>
    <root-XML localName="materialx"/>

xerxes_ · 2026-03-26 22:55:22

OK. Now I done it once more but right after I run /usr/bin/update-mime-database /usr/share/mime /usr/share/mime/model/materialx.xml file stays in directory, so it works!

seth · 2026-03-26 23:33:45

For clarification, you previously put the new materialx.xml in /usr/share/mime/model again but when using /usr/share/mime/packages everything works as expected?

If you're applying loqs' extension (and run update-mime-database to update /usr/share/mime/model/materialx), does mimetype handling still work (and does eg. file or mimetype from perl-file-mimeinfo correctly detect *.mtlx files?

<?xml version="1.0" encoding="utf-8"?>
<mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info">
  <mime-type type="model/materialx">
    <comment>MaterialX Shading Network</comment>
    <icon name="materialx"/>
    <magic priority="80">
      <match type="string" offset="0:1024" value="&lt;materialx">
        <match type="string" offset="1:128" value="version="/>
      </match>
    </magic>
    <root-XML localName="materialx"/>
    <glob-deleteall/>
    <glob pattern="*.MTLX"/>
    <glob pattern="*.mtlx"/>
  </mime-type>
</mime-info>

Yes.

When I apply loqs' extension and run update-mime-database:

# update-mime-database -V /usr/share/mime/
Updating MIME database in /usr/share/mime...

Parsing source file /usr/share/mime/packages/application-x-xpraconfig.xml...
...
Parsing source file /usr/share/mime/packages/materialx.xml...
Error in type 'model/materialx' (in /usr/share/mime/packages/materialx.xml): Missing 'namespaceURI' attribute'.
Parsing source file /usr/share/mime/packages/okteta.xml...
...

So there is only one error when mangling all xml mime files, previously it wasn't.

And this is content of /usr/share/mime/model/materialx.xml file now:

<?xml version="1.0" encoding="utf-8"?>
<mime-type xmlns="http://www.freedesktop.org/standards/shared-mime-info" type="model/materialx">
  <!--Created automatically by update-mime-database. DO NOT EDIT!-->
  <comment>MaterialX Shading Network</comment>
  <icon name="materialx"/>
</mime-type>

Run mimetype from perl-file-mimeinfo on *.mtlx files:

$ mimetype /usr/share/materialx/libraries/targets/*
/usr/share/materialx/libraries/targets/essl.mtlx:    model/materialx
/usr/share/materialx/libraries/targets/genglsl.mtlx: model/materialx
/usr/share/materialx/libraries/targets/genmdl.mtlx:  model/materialx
/usr/share/materialx/libraries/targets/genmsl.mtlx:  model/materialx
/usr/share/materialx/libraries/targets/genosl.mtlx:  model/materialx

Looks like it work. But file says that they are "XML 1.0 document, ASCII text" files.

If anyone would like to make an MR, I'd be happy to merge the fix.

loqs · 2026-03-27 17:07:43

With namespaceURI added and set to an empty string:

<?xml version="1.0" encoding="utf-8"?>
<mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info">
  <mime-type type="model/materialx">
    <comment>MaterialX Shading Network</comment>
    <icon name="materialx"/>
    <magic priority="80">
      <match type="string" offset="0:1024" value="&lt;materialx">
      </match>
    </magic>
    <root-XML localName="materialx" namespaceURI=""/>
    <glob-deleteall/>
    <glob pattern="*.MTLX"/>
    <glob pattern="*.mtlx"/>
  </mime-type>
</mime-info>

Tested with

$ git clone https://github.com/AcademySoftwareFoundation/MaterialX.git
$ cd MaterialX/
$ find . -name "*.mtlx" -exec xdg-mime query filetype {} \;

@loqs
For me version of materialx.xml from post #14 in this thread also works:

<?xml version="1.0" encoding="utf-8"?>
<mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info">
  <mime-type type="model/materialx">
    <comment>MaterialX Shading Network</comment>
    <icon name="materialx"/>
    <glob-deleteall/>
    <glob pattern="*.MTLX"/>
    <glob pattern="*.mtlx"/>
  </mime-type>
</mime-info>

After copying it to /usr/share/mime/packages/ and running 'update-mime-database -V /usr/share/mime' mimetype command also recognize mtlx files:

$ mimetype /usr/share/materialx/libraries/targets/*
/usr/share/materialx/libraries/targets/essl.mtlx:    model/materialx
/usr/share/materialx/libraries/targets/genglsl.mtlx: model/materialx
/usr/share/materialx/libraries/targets/genmdl.mtlx:  model/materialx
/usr/share/materialx/libraries/targets/genmsl.mtlx:  model/materialx
/usr/share/materialx/libraries/targets/genosl.mtlx:  model/materialx

And it don't produce error like in post #20 (probably not much visible, but still):

Error in type 'model/materialx' (in /usr/share/mime/packages/materialx.xml): Missing 'namespaceURI' attribute'.

So I don't know what your other/next versions add? Can you describe?
