New kernel 5.10 compile issue on Debian: Fatal Python error: init_fs_encoding: failed to get the Python codec of the filesystem encoding #55

Closed Intensity closed 1 year ago

Intensity commented 1 year ago

Hi,

I'm mentioning "new" because I've gotten drbd to compile just fine before, and even in the same (Debian 11/x86_64) environment.

I'm using coccinelle version 1.1.0.deb-1.1, as this comes with Debian 11 and this also appears to be a sufficient version according to the documentation. Also, Python is version 3.9. I haven't added anything to the environment.

The compile ends here:

Hi, i got into the same problem on 2 of my machines. For me, my machines are fresh installed, so i can't say it was compiling in the past.

But i wanted to share that i was able to fix this error on my machines by installing the python-is-python3 package from the debian repo.

Maybe this is useful to someone.

that is known and I had to fix the same in "spatch as a service" some months ago, adding this, and one more python dependency: https://github.com/LINBIT/saas/commit/7bef2e7976a455550bce2533487c635f20390ccf
