When I run "emerge --info" I get the following error message: # emerge --info Traceback (most recent call last): File "/usr/lib/python-exec/python3.7/emerge", line 53, in <module> retval = emerge_main() File "/usr/lib/python3.7/site-packages/_emerge/main.py", line 1265, in emerge_main action=myaction, args=myfiles, opts=myopts) File "/usr/lib/python3.7/site-packages/portage/proxy/objectproxy.py", line 31, in __call__ return result(*args, **kwargs) File "/usr/lib/python3.7/site-packages/_emerge/actions.py", line 2461, in load_emerge_config **kwargs) File "/usr/lib/python3.7/site-packages/portage/__init__.py", line 550, in create_trees env=env, sysroot=sysroot, eprefix=eprefix) File "/usr/lib/python3.7/site-packages/portage/package/ebuild/config.py", line 604, in __init__ self.packages = tuple(stack_lists(packages_list, incremental=1)) UnboundLocalError: local variable 'packages_list' referenced before assignment This problem started happening approximately at the same time when I started adding some /etc/portage configuration files to my system dotfiles, using symlinks. For example /etc/portage/make.conf is now a symlink to /etc/dotfiles/portage/make.conf. /etc/dotfiles is my git repository for system dotfiles. But I'm not sure if this is the cause of the error message. I get similar error messages with other commands such as "emaint sync -a", "emerge --depclean" and "emerge --search gcc". For obvious reasons I cannot attach my "emerge --info" log to this bug report. Reproducible: Always
Some kind of IOError triggers this, and the bug comes from this commit: https://gitweb.gentoo.org/proj/portage.git/commit/?id=55b2e1c0a51d64a84e5649c135cdbc2c650ce6ca Hopefully it will give a more meaningful error if you patch /usr/lib/python3.7/site-packages/portage/package/ebuild/config.py with a raise statement like this: > diff --git a/lib/portage/package/ebuild/config.py b/lib/portage/package/ebuild/config.py > index cc2413989..858dd324f 100644 > --- a/lib/portage/package/ebuild/config.py > +++ b/lib/portage/package/ebuild/config.py > @@ -600,6 +600,7 @@ class config(object): > if e.errno == IsADirectory.errno: > raise IsADirectory(os.path.join(self.profile_path, > "packages")) > + raise > > self.packages = tuple(stack_lists(packages_list, incremental=1)) >

I edited /usr/lib/python3.7/site-packages/portage/package/ebuild/config.py as you said. Now I get the following error message: # emerge --info Traceback (most recent call last): File "/usr/lib/python-exec/python3.7/emerge", line 53, in <module> retval = emerge_main() File "/usr/lib/python3.7/site-packages/_emerge/main.py", line 1265, in emerge_main action=myaction, args=myfiles, opts=myopts) File "/usr/lib/python3.7/site-packages/portage/proxy/objectproxy.py", line 31, in __call__ return result(*args, **kwargs) File "/usr/lib/python3.7/site-packages/_emerge/actions.py", line 2461, in load_emerge_config **kwargs) File "/usr/lib/python3.7/site-packages/portage/__init__.py", line 550, in create_trees env=env, sysroot=sysroot, eprefix=eprefix) File "/usr/lib/python3.7/site-packages/portage/package/ebuild/config.py", line 598, in __init__ for x in profiles_complex] File "/usr/lib/python3.7/site-packages/portage/package/ebuild/config.py", line 598, in <listcomp> for x in profiles_complex] File "/usr/lib/python3.7/site-packages/portage/util/__init__.py", line 478, in grabfile_package pkgs=grabfile(myfilename, compatlevel, recursive=recursive, remember_source_file=True) File "/usr/lib/python3.7/site-packages/portage/util/__init__.py", line 131, in grabfile mylines = grablines(myfilename, recursive, remember_source_file=True) File "/usr/lib/python3.7/site-packages/portage/util/__init__.py", line 574, in grablines mode='r', encoding=_encodings['content'], errors='replace') as myfile: NotADirectoryError: [Errno 20] Not a directory: b'/etc/portage/profile/packages' On my system /etc/portage/profile is a symlink to /etc/dotfiles/portage/profile. The latter is a regular file, not a directory. With the following content: -*sys-apps/openrc -*sys-apps/busybox -*sys-apps/net-tools I fixed the problem by making /etc/portage/profile a directory and moving the previous three lines to /etc/portage/profile/packages: # ls -l /etc/portage/profile/packages lrwxrwxrwx 1 root root 38 Jun 10 21:31 /etc/portage/profile/packages -> /etc/dotfiles/portage/profile/packages Now I can run "emerge --info" without any problems!
