Was able to correct by editing the following in /var/lib/dpkg/info/plexmediaserver.postinst: line 697 and 698:

[ $DistroName = “ubuntu” ] && [ $DistroVersion -gt 2000 ] && UseGpg=1
[ $DistroName = “debian” ] && [ $DistroVersion -ge 1000 ] && UseGpg=1

with " " around $DistroName, re-ran script plexmediaserver.postinst and no longer received error.

What exact Distro and shell? I installed on Debian 10 without issue and the script already had quotes around the distro’s.

My next concern is why DistroName isn’t populated which would have worked regardless of quotes.

Is /bin/bash linked to something else ?

Renegade9 · August 9, 2022, 2:28am

Hi,

Sorry for the confusion, it was erroring because “” was not around $DistroName variable ie “$DistroName” not “” around ubuntu or debian

Corrected code should be:

[ "$DistroName" = "ubuntu" ] && [ $DistroVersion -gt 2000 ] && UseGpg=1
[ "$DistroName" = "debian" ] && [ $DistroVersion -ge 1000 ] && UseGpg=1

Debian Linux 11
Kernel: Linux 5.16.0-0.bpo.4-amd64 on x86_64

Edit:
Confirmed issues is still happening with latest dev build, same resolution to correct error

ChuckPa · August 9, 2022, 2:45am

Again, I am not understanding. There should be no errors at all.
The line number being reported makes no sense whatsoever.

DistroName is returned by quering /etc/os-release

DistroName="$(grep ^ID= /etc/os-release)" ; DistroName="${DistroName//[^.]*=/}"

Can you show me your /etc/os-release?

Renegade9 · August 9, 2022, 2:50am

PRETTY_NAME=“Debian GNU/Linux 11 (bullseye)”
NAME=“Debian GNU/Linux”
VERSION_ID=“11”
VERSION=“11 (bullseye)”
VERSION_CODENAME=bullseye
ID=debian
HOME_URL=“https://www.debian.org/”
SUPPORT_URL=“https://www.debian.org/support”
BUG_REPORT_URL=“https://bugs.debian.org/”

If I run the following:

DistroName="$(grep ^ID= /etc/os-release)" ; DistroName="${DistroName//[^.]*=/}"
echo $DistroName
debian

Here is a stack overflow about this same error with variable comparisons:

ChuckPa · August 9, 2022, 2:53am

ID=debian

is exactly what I expect.

Please observe.

[chuck@lizum debian.2007]$ DistroName="ID=debian"
[chuck@lizum debian.2008]$ DistroName="${DistroName//[^.]*=/}"
[chuck@lizum debian.2009]$ echo $DistroName
debian
[chuck@lizum debian.2010]$

There is no reason it should fail for you when it works on Ubuntu

    # Where is Beignet available and viable ? (below 21.04)
    [ "$DistroName" = "ubuntu" ] && [ $DistroVersion -lt 2100 ] && BeignetAvailable=1
    [ "$DistroName" = "debian" ]                                && BeignetAvailable=1

There must be a reason… but what is it???

I will quickly setup a new Debian 11 and retest

ChuckPa · August 9, 2022, 3:03am

done. Here we are.

Hi ChuckPa,

Thanks for such a quick reply. Please note the use of “” around $DistroName if the code you posted above for your comparison of “$DistroName” = “debian” within single . With that it will work as intended, however lines 697 and 698 are missing “” around $DistroName within /var/lib/dpkg/info/plexmediaserver.postinst.

This can be solved by either using [] around the variable comparison or by editing the lines to be “$DistroName” instead of $DistroName

ChuckPa · August 9, 2022, 3:05am

Please look above.

Using the current beta, which I just downloaded, I cannot reproduce your failure.

Renegade9 · August 9, 2022, 3:09am

Hi ChuckPa,

Does line 697/698 in /var/lib/dpkg/info/plexmediaserver.postinst on your machine contain:

[ $DistroName = "ubuntu" ] && [ $DistroVersion -gt 2000 ] && UseGpg=1
[ $DistroName = "debian" ] && [ $DistroVersion -ge 1000 ] && UseGpg=1

or

[ "$DistroName" = "ubuntu" ] && [ $DistroVersion -gt 2000 ] && UseGpg=1
[ "$DistroName" = "debian" ] && [ $DistroVersion -ge 1000 ] && UseGpg=1

ChuckPa · August 9, 2022, 3:09am

No they do not nor do they need it.

chuck@debian11:~/Downloads$ A=hi
chuck@debian11:~/Downloads$ [ $A = hi ] && echo YES
YES
chuck@debian11:~/Downloads$ [ $A = low ] && echo YES
chuck@debian11:~/Downloads$

= is already a string comparison operator.
"thing* Something" prevents unexpected globbing and allows inclusion of spaces, neither of which can appear in the value.

Renegade9 · August 9, 2022, 3:30am

Hi,

Would you be able to provide the query used for $DistroVersion? Just to double check manually to make sure the query would work with the rest of the && statement on my machine.

The only other thing I could think of is if $DistroName isn’t being populated correctly within the script causing a none existing value to be compared to.

I noticed the following setting variables at the top of /var/lib/dpkg/info/plexmediaserver.postinst but haven’t dug elsewhere in the code for it

DistroName="$(GetConfig DistroName)"
DistroVersion="$(GetConfig DistroVersion)"

ChuckPa · August 9, 2022, 3:32am

The function GetConfig() is used to pass info from preinstall → postinstall.

I write the results of preinst to /tmp/plexinstaller.log
To prevent privilege escalation attacks, I use GetConfig to read the values from /tmp/plexinstaller.log and set the corresponding variables in postinst for use.

ChuckPa · August 9, 2022, 3:34am

I noticed you’re using 1.28.1.6018. I’m not familiar with that build. (never saw it)
I am familiar with PlexPass version

plexmediaserver_1.28.1.6041-738907df3_amd64.deb

Would you mind downloading and installing?

Renegade9 · August 9, 2022, 3:40am

Hi,

I originally saw the error with 1.28.1.6018 but have since updated as well to 1.28.1.6041, the install logs are above but I will just post them again for ease of use.

Now I have to point to your machine RELUCTANTLY.

Which specific Debian 11 update are you running? I am 11.3
Does it have all updates ?

There is something afoot in that install. It’s annoying me

Renegade9 · August 9, 2022, 3:52am

Hi,

I am not sure what subversion (If you know the command I can run it) but here is my current config:

 uname -r

ChuckPa · August 9, 2022, 3:53am

That’s not the default 11.3 kernel.
Debian usually lags behind everyone else.
Ubuntu is shipping 5.15 kernel.

You installed that yourself?

5.16.0-0.bpo.4-amd64 kernel was installed through backports, I needed it for better support for a few drivers/devices and for updated zfs version for my system
