 Posted: Thu Nov 28, 2024 8:49 am Post subject: I clobbered my package.use |
 |
|
This is not a cry for help. If it were, this topic wouldn't have been opened in "Gentoo Chat" subforum.
I'm just posting my first linux mistake in years.
Most of my package.use contents are in package.use/custom.
Yesterday I realized that media-gfx/feh can open urls of images if compiled with the curl USE flag.
To try it out, I ran USE=curl emerge feh and it worked great!
I was feeling lazy and did not want to open my editor to commit the USE change to my package.use.
Instead I ran | Code: | | echo 'media-gfx/feh curl' | sudo tee /etc/portage/package.use/custom |
Next I wanted to update my system and was greeted with | Code: | !!! Problem resolving dependencies for sys-apps/util-linux from @system
... done!
Dependency resolution took 1.17 s (backtrack: 0/20).
!!! The ebuild selected to satisfy "sys-apps/util-linux" has unmet requirements.
- sys-apps/util-linux-2.40.2::gentoo USE="cramfs hardlink logger ncurses readline su suid udev (unicode) -audit -build -caps -cryptsetup -fdformat -kill -magic -nls -pam -python (-rtas) (-selinux) -slang -static-libs -systemd -test -tty-helpers -uuidd -verify-sig" ABI_X86="(64) -32 (-x32)" PYTHON_TARGETS="-python3_10 -python3_11 -python3_12"
The following REQUIRED_USE flag constraints are unsatisfied:
su? ( pam )
The above constraints are a subset of the following complete expression:
python? ( any-of ( python_targets_python3_10 python_targets_python3_11 python_targets_python3_12 ) ) su? ( pam ) |
Well... I know what I've done wrong... |

gentoolkit will help you :
| Code: | | enalyze rebuild -p use |
Remove '-p' to create a file.
As said by the command :
| Quote: | -- Scanning installed packages for USE flag settings that
do not match the default settings
-- These are the installed packages & use flags that were detected
to need use flag settings other than the defaults. |
EDIT : enalyze don't take into account global useflags in /etc/portage/make.conf |

| Nice! I was planning on writing something similar, by parsing /var/db/pkg, but enalyze will be a nice shortcut. |

Interesting...
Baclk in time; I wish I had known that.
My way to fix was much harder...
Currently have one file per CATEGORY/PACKAGE which has its pro and con.
Risk remains however. Recovery will hence be much easier.
Thks 4 ur attention, interest & support.

You might benefit from having a system in place for automatically creating regular backups, preferably on a separate drive.
In the future, you could easily restore damaged or corrupted files from a backup in just a few seconds.
My IT professors used say, "Backups, Backups, Backups!". |
