Linux PMS 1.28.1.6018-c1f308c6a Install Error

Plex Media Server
42

The issue is here in this line:

...
if [ "$(grep -zi '^container=.\+$' /proc/1/environ )" != "" ]; then
...
43

If you go to /var/lib/dpkg/info, you can find the script itself.

My concern is container detection is long-stable code. I donā€™t understand why it would suddenly change.

[chuck@lizum ~.1999]$ cd /var/lib/dpkg/info/
[chuck@lizum info.2000]$ ls plex*
plexmediaserver.list     plexmediaserver.postinst*  plexmediaserver.preinst*
plexmediaserver.md5sums  plexmediaserver.postrm*    plexmediaserver.prerm*
[chuck@lizum info.2001]$

# Independently,  evaluate if in a LXC.  This is used later in installation to avoid UDEV trigger bug
# Look only for a the prefix 'container='.  No further refinement needed as docker already handled above.
if [ "$(grep -zi '^container=.\+$' /proc/1/environ )" != "" ]; then
  LinuxContainer=1
fi

I just opened a LXC. I found it but not sure why yet.

root@media:~# LinuxContainer=0
root@media:~# if [ "$(grep -zi '^container=.\+$' /proc/1/environ )" != "" ]; then
>   LinuxContainer=1
> fi
bash: warning: command substitution: ignored null byte in input
root@media:~# if [ "$(grep -Zi '^container=.\+$' /proc/1/environ )" != "" ]; then   LinuxContainer=1; fi

Iā€™m more than rusted about regex, but I think you are trying to find out if there is a variable starts with ā€œcontainer=ā€ ignoring lower or upper cases.
This is how the file looks like in my LXC:

TERM=linuxcontainer=lxccontainer_ttys=pts/1 pts/2

And here is the reason, why there is this warning here:
https://lists.gnu.org/archive/html/bug-bash/2016-09/msg00015.html

hereā€™s what you get from cat /proc/1/environ

root@media:~# cat /proc/1/environ
container=lxcroot@media:~#

Notice itā€™s null terminated.

Iā€™m looking for container=.

Reading ā€“ Wonderful. Bash changed.

47

Isnā€™t this better?

# grep -zq "container=lxc" /proc/1/environ && echo LXC || echo notLXC
LXC

Because in my proc/1/environ (see previous comment) the line with container begins with ā€œlinuxcontainerā€.

I have this LXC on proxmox 7-2.7.

48

Are the choices Zi or zq ?

Proxmox is its own beast. Itā€™s a BEAR to support and why we canā€™t

49

q is just for quiet. i is for ignore upper or lower case. Iā€™m not sure about zā€¦

50

If you generlize the line, it should just for proxmox LXCs also. nothing to support proxmox specific here.

51

Do you know a way for me to get Proxmox into a standard (ESXi) VM?

52

Yeah, just create a normal VM or a VM in Virtualbox.

53

Here are some links for you:
https://pve.proxmox.com/wiki/Proxmox_VE_inside_VirtualBox

54

I have VMware Workstation and ESXi (on the big machine). Proxmox is too smart for Workstation.

55

It should be similar, just create a VM with a minimal storage (1 virtual drive) and install it over a BIOS (or EFI, as it supports it too).

Edit: One more link for ESXi

56

Any licensing required?

57

No, you can use community license and the community repositories.

58

Thanks. I will try this again. Last I tried it was Proxmox 6.

Itā€™s even better now. Let me know, if you need something with your proxmox setup.

For the LXC, I used the default debian11 image:

61

I will. Iā€™ll also setup a Ubuntu LXC because that is another common one
