(Solved)Error trying to update

[DarkYamik]

Hello there! I’ve noticied that today after seeing the update available I clicked on it and i got the following error:

        Traceback (most recent call last):

File “/opt/rockstor/src/rockstor/storageadmin/views/command.py”, line 193, in post

After getting this, now i can’t see the current version that I’m using right now and i can’t update anymore.

Maybe I have a wrong version of the date parser?

[phillxnet (Philip Guyton)]

@DarkYamik Hello again.

Yes this one is strange as we use yum’s changelog plugin and in one report the required date parse was not installed, yet it’s supposed to be a dependency of the changelog plugin. This was reported over in the following forum thread:

Unable to check update

@kysdaddy Welcome to the Rockstor community. Well that’s weird as you appear to be missing a package. All my systems here have it. Very starnge. Way back this was an issue upstream where yum-changelog has a missing dependency on python-dateutil ie: https://bugzilla.redhat.com/show_bug.cgi?id=674468 ie my systems respond thus: yum list installed | grep dateutil python-dateutil.noarch 1.5-7.el7 @base Try the following command as root: yum install python-dateutil…

But your report is a little different:

@DarkYamik

Maybe I have a wrong version of the date parser?

As you say the parser does seem to be installed but is not recognising the “2017-Dec-29” string as containing a date from the CommandException:

cmd = /usr/bin/yum changelog 2017-Dec-29 rockstor

with the “raise ValueError(“String does not contain a date.”)” return.

And that command works without error here.

What is the result of the following command:

yum info python-dateutil

I get:

@DarkYamik

After getting this, now i can’t see the current version that I’m using right now and i can’t update anymore.

No worries on the update as you can always update via the command line by running the following as root:

yum update rockstor

and to view the installed and available versions you can do:

yum info rockstor

obviously a work around but just while we get to the bottom of this.

Have you tried doing a general update via the UI, ie all packages bar the rockstor one. It’s available via a flashing icon to the left of the word “Linux” in the top right of the UI (only shows up if any are available).

It could be we are hitting a bug in an older version of the “python-dateutil” but seems unlikely. But the string clearly does contain a date.

My initial suspicion in your case is that we have a regional issue as we execute all commands as if they were en_US ie:

rockstor/rockstor-core/blob/master/src/rockstor/system/osi.py#L96-L106

But I would still have expected dateutil to have worked.

Thanks for the report and let us know how you get on with those commands.

[DarkYamik]

Thank you for the fast reply!

I tried the command on the command line and I get the same error

The outpout is exactly the same as yours

I tried to update via CLI and UI, but from the UI I get the error we are talking about and i can’t even see the version i’m using.

Rockstor version is 3.9.2 by the way

I thought the same, but I’m using en_US locals to avoid problems regarding them

@phillxnet

My initial suspicion in your case is that we have a regional issue as we execute all commands as if they were en_US ie:

rockstor-core/osi.py at master · rockstor/rockstor-core · GitHub

But I would still have expected dateutil to have worked.

Thanks for the report and let us know how you get on with those commands.

This is the outpuu from the LANG variable

[root@yaminas ~]# echo $LANG
en_US.UTF-8

Thank you for your help!

[DarkYamik]

Okay I found what seems to be the problem. On the file that shows the error
(nano /usr/lib/yum-plugins/changelog.py), there is the following line 215

                if self._since_dto == dateutil_parser.parse('garbage', fuzzy=True):
                    # 'since' was a package name, not a date
                    extcmds.insert(0, since)

If i change the ‘garbage’ variable to 2017-Dec-29 as it follows

                if self._since_dto == dateutil_parser.parse('2017-Dec-29', fuzzy=True):
                    # 'since' was a package name, not a date
                    extcmds.insert(0, since)

If I do this, everything is working fine and updates are working correctly. For what i can see, the argument provided plain text is not a date so thats why it shows the error

[DarkYamik]

Okay, I found it i needed to change the variable and everything works fine right now

                if self._since_dto == dateutil_parser.parse(since, fuzzy=True):
                    # 'since' was a package name, not a date
                    extcmds.insert(0, since)

I don’t know why it was like that though, maybe is a generalized error?

[phillxnet (Philip Guyton)]

@DarkYamik Nice debugging there.

@DarkYamik

Okay, I found it

and from the following:

rpm -qf /usr/lib/yum-plugins/changelog.py
yum-plugin-changelog-1.1.31-42.el7.noarch

we have that file belonging to the package:

yum-plugin-changelog

with:

But I have the exact same line in my version and it isn’t throwing the error here:

                    # 'since' was a package name, not a date

Do you have the exact same version of “yum-plugin-changelog”?

Well done researching this, but I don’t think we are quite at the root of it just yet.

My LANG:

echo $LANG
en_GB.UTF-8

But as stated previously it also doesn’t fail when run via run_command’s faked US either.

@DarkYamik

I don’t know why it was like that though, maybe is a generalized error?

Yes, I think for some reason your setup is failing through to that error which is not what I’m seeing here.

And just to cover this one I have tried the problem command without error on the exact same version of rockstor as yours ie:

yum info rockstor

just in case installed / available versions are some how triggering something:

So still a bit of a puzzle.
