Can't update to January release


#21

The problem might be caused by inappropriate permissions on some of the APT key files.

Do the errors only affect OSMC packages or also Debian packages? Should we checked the permissions of /etc/apt/trusted.gpg.d?

The user might be squashing some of these permissions.

#27

What should I do now? I haven’t done any changes to NFS root since forever. Once it was set up using wiki and forums it was working. Till now. Are you thinking about something or that’s it? If there’s anything you would like to check just let me know.


#28

Probably worth seeing the permissions of the APT key files so we can compare them on non-NFS installations.

Unfortunately I don’t know what the issue is at this time. Someone needs to test that NFS installation functionality still works as expected.


#29

In addition to what Sam has requested, please show the output from the following commands:

mount
sudo apt-get -o Debug::Acquire::Transaction=true update 2>&1 | paste-log
sudo apt-get -o Debug::Acquire::http=true update 2>&1 | paste-log
sudo apt-get -o Debug::Acquire::gpgv=true update 2>&1 | paste-log

#30

Where should I look for those APT keys? I’m not very familiar with terminal. I know few things but nothing fancy.


#31

The APT keys are in /etc/apt and /etc/apt/trusted.gpg.d

Use ls -la for both directories.

#35

Those three files were created by the paste-log command and should be owned by user osmc, not by root. What happens if you run:

touch /tmp/zzztest
ls -l /tmp/zzztest

Looking at the third command:

sudo apt-get -o Debug::Acquire::gpgv=true updatei

we can see that it runs various /usr/bin/apt-key commands, which all fail with a return code of 1. So let’s try a few ourselves:

/usr/bin/apt-key --readonly verify  /tmp/apt.sig.8WnzS5 /tmp/apt.data.KGmBaz
/usr/bin/apt-key --readonly verify /var/lib/apt/lists/partial/ftp.debian.org_debian_dists_stretch_Release.gpg /var/lib/apt/lists/partial/ftp.debian.org_debian_dists_stretch_Release

I’ve removed the “–status-fd 3” part because it causes an error for me and doesn’t even appear in the man page for apt-key!

Looks like we have an issue with /tmp. :wink:

Please run those two apt-key commands using sudo.

#39

I wasn’t sure if anything would be in the “partial” directories - and it looks like the files weren’t there. No problem, since the other command worked.

Let’s try a few things more:

rm /tmp/zzztest

and if that doesn’t work:

sudo rm /tmp/zzztest

If you could run exportfs -v on the Synology box that would be useful.


#40

removing from /tmp required sudo.
exportfs looks like this

admin@DS:~$ sudo exportfs -v
Password:
/volume4/Anime (rw,async,insecure,no_root_squash,no_subtree_check,insecure_locks,anonuid=1025,anongid=100,sec=sys,rw,no_root_squash,no_all_squash)

/volume1/osmc2 (rw,async,crossmnt,insecure,root_squash,all_squash,no_subtree_check,anonuid=0,anongid=0,sec=sys,rw,root_squash,all_squash)

NFS root from Pi’s are osmc and osmc2.


#41

This isn’t a good way to do things:

root_squash,all_squash,anonuid=0,anongid=0

maps everything to root, even when it shouldn’t be, eg user osmc’s files should be owned by uid 1000, not by uid 0.

I’m not really sure how it affects your updates but I’d recommend that you change it simply to no_root_squash and re-export the share using exportfs -r.

This aplies to osmc and osmc2. Try one first and see if it makes a difference.


#42

Squashing root has never been supported by OSMC. This has probably been working out of sheer luck in the past.

We have some guidance on a suitable exportfs somewhere IIRC. In Raspbmc we used to tell the user what was acceptable via the installer. Maybe we should start doing this again in the future

In Stretch, certain apt operations are sandboxed by an _apt user. I suspect the lack of proper ownership here is causing the update problems


#43

I reckon that’ll be the cause.


#46

I will try that today when I get back home. Is there any chance that the install might broke after that? I don’t want to be forced to reinstall everything. In fact maybe I will create new share with new settings and try it? I’d like to have it like it should be. Maybe you could write how export should looks like for NFS root?

Edit:
I’ve tried to install in a new directory. After first part, installer downloaded and placed files in NFS root on Synology. After the restart it did some more but next I saw sad face. And from now on, there’s a loop of sad face and restart of Pi.

Edit2:
When I create new NFS share these are default options:
/volume1/test <world>(rw,async,crossmnt,insecure,no_root_squash,no_subtree_check,insecure_locks,anonuid=1025,anongid=100,sec=sys,rw,no_root_squash,no_all_squash) Maybe it’ll help somehow.

Edit3:
I did chmod 555 to my test share and OSMC installed properly. Also as I choose to install 2017-12-1 I’m now able to update to 2018. I hope as it’s happening right now. I have found exact export here [Resolved] Impossible to do a NFS installation and I will try to change and see what will happen with my existing osmc shares.


#47

There’s no need for insecure or anonuid=1025,anongid=100. All UIDs must come from the OSMC installation, so there’s no reason for having anonuid or anongid in your /etc/expoorts line.
