 |
|
I have strange problem. I'm trying to run Gentoo in chroot on Synology. Till recently (at least 3 years long) everything was fine, but about one month ago I did an update and since then I can't install any packages.
At first I thought it could be some problem with switching to new CHOST. So, I've downloaded fresh stage3, unpacked it, chrooted and tried to build simple package. The compilation itself goes without problem, but installation fails again with the same error. Here it is:
| Code: |

I can only guess, that new portage uses some kernel calls that are not supported by kernel provided by Synology. It runs kernel 3.2.40. So, my question, is there any way to work around this conflict? |

Update to a newer kernel. v3.2.40 was released in March 2013. The v3.2 line is still at least somewhat maintained, with v3.2.102 released June 2018. However, for this purpose, I would suggest updating at least to a kernel whose major version was current when Python 3.6 was released. Preferably, update to a kernel that is still supported upstream.
You could also try using Python2.7 and hope that the dependency was not backported. |

| I wish I could. Updating Synology kernel is out of my options. They use Linux, but they customize it heavily, so there's no (easy) way to install custom packages. That is why I was using Gentoo in chroot. Well, seems like this option is also a "no-go" now. |

| The core kernel has a strong policy against breaking userspace on upgrades, even when userspace was wrong. Unless the Synology kernel has been badly hacked on, you can probably switch to a newer kernel. If it has been mangled, you should bug your vendor for a kernel update. There have been many security fixes since the version currently installed on that system, so an upgrade is advisable independent of whether it helps here. |

Well, for the time of waiting till Synology updates kernel I've found work-around. It is not perfect since may raise issues when python library is updated, but for the time being it is simple and acceptable.
I've opened file /usr/lib/python3.6/site-packages/portage/util/file_copy/__init__.py and replaced
| Code: |
try:
from portage.util.file_copy.reflink_linux import file_copy as _file_copy
except ImportError:
_file_copy = None
|
with
| Code: |
#try:
# from portage.util.file_copy.reflink_linux import file_copy as _file_copy
#except ImportError:
_file_copy = None
|
Now I can install packages again. |

Just to confirm, I experience the same problem on a 4.9 kernel on a standard Intel Atom x86 machine. This is a 32-bit system, and I get the exact same error on some packages. However it is not always consistent.
I have tested all these portage version: 2.3.8, 2.3.40-r1, 2.3.49, 2.3.51-r1 (default) and 2.3.52-r1.
The only one that works well without a fix is 2.3.8. But that one has other issues like not understanding EAPI7.
Your patch to the python file works also. |
