 |
|
When attempting to start Evolution I get
| Code: |
bwrap: Creating new namespace failed, likely because the kernel does not support user namespaces. bwrap must be installed setuid on such systems.
|
I think I have namespace set up in the kernel, but you tell me. Below is what I see when I search for "namespace" in menuconfig:
| Code: |
Symbol: MODULE_ALLOW_MISSING_NAMESPACE_IMPORTS [=n] │
│ Type : bool │
│ Defined at init/Kconfig:2172 │
│ Prompt: Allow loading of modules with missing namespace imports │
│ Depends on: MODULES [=y] │
│ Location: │
│ (1) -> Enable loadable module support (MODULES [=y]) │
│ │
│ │
│ Symbol: NAMESPACES [=y] │
│ Type : bool │
│ Defined at init/Kconfig:1056 │
│ Prompt: Namespaces support │
│ Depends on: MULTIUSER [=y] │
│ Visible if: MULTIUSER [=y] && EXPERT [=n] │
│ Location: │
│ (2) -> General setup │
│ Selected by [y]: │
│ - GENTOO_LINUX_PORTAGE [=y] && GENTOO_LINUX [=y]
|
Do I need to do more with the kernel? Or do I need to install something that provided bwrap?
Thank you. |

Yes, you will need CONFIG_USER_NS. This is:
| Code: | General setup --->
-*- Namespaces support --->
-*- User namespace |
... BUT ... I see you are using gentoo-souces, and then it is enabled by default too:
| Quote: | ...
Selected by [y]:
- GENTOO_LINUX_PORTAGE [=y] && GENTOO_LINUX [=y] |
Maybe you have hardening settings from KSPP in your /etc/sysctl.conf ... check if you have:
| Code: | # Disable User Namespaces, as it opens up a large attack surface to unprivileged users.
user.max_user_namespaces = 0 |
If yes, this cause the problem ...
