The first big wins are to delete the 28 and 29 from under PackageKit. 
Those are old cached update files that were never used and for a while 
PackageKit didn't clean up after itself.  You don't show what's really 
under /var/cache/yum, but anything under there can be deleted.  The 
worst case is that some metadata will need to be downloaded again. 
/var/cache/tmp has a lot of space.  I don't even have that directory. 
What's in there.  It most likely can be deleted as well.

Well, yes.  One could add a file in /etc/logrotate.d with the necessary info to 
do that.
But since the log files are only useful when a compile fails and one (me?) 
would need to expend
time thinking how to construct the /etc/logrotate.d file I'm inclined to take 
the lazy route.  :-)

2 things pop out to me.

You have a /var/cache/PackageKit/28 directory structure.  Since you're at F30 
you should also have a
/var/cache/PackageKit/30 directory structure which is now being used.  So, the 
28 is no longer being
used and can be removed.

[egreshko@acer PackageKit]$ pwd
/var/cache/PackageKit
[egreshko@acer PackageKit]$ ls
30

Is all I have on my F30 systems.

And then,

/var/cache/abrt-di/usr

That most likely contains a bunch of core files that are no longer needed.

How they get baobab out of "Gnome Disk Analyzer" is beyond me.

Done.  I'll put new statistics in a response to Samuel.

How can this be automated such that each week, when I do my patches (dnf

this require enhancements to dnf?



It has nothing to do with dnf.  Potentially you could file a bugzilla with 
rpmfusion to ask for
an enhancement to akmod-nvidia.

However, the quickest/easiest solution is to create a cron job to cleanup the 
directory on a periodic basis.

Ed appears to be correct.  I did "ls -la" on that directory.  The results are 
long, so I fpasted them in a text file here:
"https://paste.fedoraproject.org/paste/F74iI--P5MbZewNQIjjrpw";
That's a lot of files.  I'll ask the question the way I hope makes the answer

Actually, none.

Once the rpm is installed, there really is no real reason to keep them around.

You can delete them all, especially the log files.  If you really want you can 
keep the last rpm file which
matches your running kernel.

directories until you understand what's using the space.  Something fun 
and maybe useful is to try running "du -h | sort -hr | head -20".  That 
will give you the top 20 directories for disk usage.


What I would recommend is just using the Gnome disk analyzer.  The only 
difficulty is that for it to be fully useful, it needs to run as root 
which may not work if you're running Wayland.  Run "sudo baobab" from a 
terminal.  If that doesn't work, then try choosing the "Gnome on Xorg" 
option from the login screen.  (Click the gear after clicking on your 
name before entering the password.)

Done. Thank-you.

I was taught to get the advice of 2 or 3 wise friends where practical; 
it's in the Bible somewhere (I wish I could remember where!).  So you 
and Samuel agreeing gives me much more confidence. Likewise when Samuel 
and Terry agreed on a key step last week.  So regarding "FYIW": it's 
worth a lot to me!

I just looked; you're right.  Several minutes ago, I opened a new thread 
for the '/' filsystem problem.  I'll continue this there.


Thank-you, Ed.

You may find you have old files that could be deleted.

For example, if you use the akmod package for nVidia drivers they are 
automatically rebuilt on each

too-nearly-full filesystem '/'. (was upgrade problem: space on '/' filesystem.)

[home user]

(Fedora-30; x86-64; personal workstation)
This problem goes back to last Thursday, so a brief review might be good.

brief background

Last Thursday, I tried to upgrade from Fedora-29 to Fedora-30.  dnf 
complained it didn't have enough space in the '/' filesystem.  List 
members successfully got me through the upgrade.  But the root 
problem(s) probably still remains.

And who is the "sys.admin" and does the "sys.admin"-tasks on your box ?

according to this link:
https://dnf-plugins-extras.readthedocs.io/en/latest/system-upgrade.html

there is no explanation of 'dnf system-upgrade clean' !

so what it really does I don't know, but (I guess) it mainly removes stuff you 
don't need anymore ! 
stuff that was only necessary for the upgrade process/task. I guess mainly 
packages which are installed or somewhat better: the contents of these packages 
is copied to their target directories (see below).

for 'dnf clean packages' 
see
https://dnf.readthedocs.io/en/latest/command_ref.html#clean-command

the command cleans under /var/cache/dnf/ and this directory is filled/updated 
(again !!!) during any run of "sudo dnf upgrade"

so if you clean there there is no harm !

why ?

a try of an explanation:
==
lets say you want upgrade/install a package and let's say it's name is 
"config.rpm". 
let's assume it contains mainly configuration files for the target directory 
/etc

if you do "dnf upgrade" or "dnf install config.rpm" mainly two tasks are 
executed:
a) config.rpm is downloaded (!) to /var/cache/dnf
and
b) config.rpm is installed (!), what mainly means it's contents is "copied" to 
it's target directory /etc 

after both tasks there is no need to keep the packages "config.rpm" under 
/var/cache/dnf/ anymore.
after installation it has done it's purpose !

with other packages it works analogous -maybe other target directories are 
involved-

Okay ?

The second question/issue is hopefully quick and easy.  This is, I 
think, simply a matter of tying up loose ends rather than recovering a 
lot of space.  Last Thursday, as suggested by Samuel and "seconded" by 
Terry, I did these:

mv /var/lib/dnf/system-upgrade /home
ln -s /home/system-upgrade /var/lib/dnf

sigh.  How did I miss that?  (don't answer!)  You're correct.  It's for

Gnome has built-in screen sharing, but you need a separate channel for 
audio.  It also doesn't work through NAT because that would require an 
outside server.

Mostly agree.  Let's put this aside for now, deal one two other upgrade 
questions/issues, and then handle the too-nearly-full filesystem in a 
separate thread.  But I think ultimately, the junk ought to be properly 
identified and cleaned out.


Personally, I don't think it's worth the effort to figure out what 
little can be removed.



The first upgrade question/issue:

During the download phase, dnf displayed the following:
-
Running transaction test The downloaded packages were saved in cache 
until the next successful transaction. You can remove cached packages by 
executing 'dnf clean packages'.

-
and when re-doing the download, dnf displayed the following:
-
Download complete! Use 'dnf system-upgrade reboot' to start the upgrade.
To remove cached metadata and transaction use 'dnf system-upgrade clean'
The downloaded packages were saved in cache until the next successful 
transaction.

You can remove cached packages by executing 'dnf clean packages'.
-
My sense is that those two dnf commands are things the sys.admin. does 
if something goes wrong and he has to back-track (or start over).  Am I 
correct, or should I do those?  By the way, the dnf man page makes no 
mention of a system-upgrade command.


The first one is specific to the system-upgrade plugin because it puts 
the files in a different cache location than normal dnf.  You would only 
need that if you decide not to do the upgrade and want to get the space 
back.  Or very unlikely, in case something really went wrong and dnf 
can't recover from some corrupted files.


The second one is just the standard bit that dnf always puts at the end 
if you don't actually run the transaction (e.g. --downloadonly).  The 
same reasons as the other one.

Last Thursday, I came "that close" to running that
"dnf remove $(dnf repoquery --extras --exclude=kernel,kernel-\*)".
Looks like it's a good thing that I didn't.  It looks like I understood

You can remove cached packages by executing 'dnf clean packages'.
-
My sense is that those two dnf commands are things the sys.admin. does 
if something goes wrong and he has to back-track (or start over).  Am I 
correct, or should I do those?  By the way, the dnf man page makes no 
mention of a system-upgrade command.


Let's deal with this one first, then I'll post the second.

thanks,
Bill.

Two way trust IPA <--> AD

[Michal Zacek]

Hello,

it is possible to use an IPA accounts to login to the AD domain 
(cross-forest trust)? I would need create a file share on Windows, which 
should be accessible by IPA users. I know the opposite (AD --> IPA) work 
well, but after i read all docs, I came to conclusion that this so 
called "two way trust" is in reality only one way trust.


Thanks for any help.
Best regards,
Michal

remove elder kernels and elder modules:


1.
rpm -qa | grep kernel-core

2.
sudo dnf remove 

means all F29 and maybe elder F30 kernels (for F30 carefully read the version 
numbers)
if unsure leave F30 kernels, they will removed automatically when newer kernels 
gets installed via upgrade.

ever, carefully read what dnf wants to remove !
usually it is (on a box WITHOUT nvidia !):
- kernel
- kernel-core
- kernel-modules

2b.
sudo dnf remove kernel-devel < for the kernel-versions you removed in step 2.>
 
kernel-devel is needed to compile your kmod-nvidia.
if unsure leave for F30.

3.
to fix grub entries after removing kernels:
[ -d /sys/firmware/efi/efivars ] && sudo grub2-mkconfig -o 
/boot/efi/EFI/fedora/grub.cfg || sudo grub2-mkconfig -o /boot/grub2/grub.cfg

- last line is ONE line ([ ... .cfg] -

4.
rpm -qa | grep kmod-nvidia

5.
sudo dnf remove 

carefully read what dnf wants to remove !
don't remove the nvidia package, only kmod-nvidia !
if unsure leave all F30 kmod-nvidia !

extra:
 
kmod-nvidia are automatically compiled for the running kernel and gets 
installed.
kmod packages are kept on your box under
 /usr or /var

- I don't know exactly, cause I don't run nvdia here (only VBOX), so maybe I'm 
wrong -

e.g. find /usr -iname '*kmod-nvidia*' will find the directory
I guess there are a lot of elder kmod's in...


packages clean up
===
as mentioned do a research !

one research could be:

for each package in your list you provided on "Montag, 14 Oktober"
find out if a package for F30 is installed beside elder one's:

rpm -qa | grep 

if a package is installed for F30 and you got elder one e.g. for F29 do

sudo dnf remove 

carefully read what dnf want's to remove !
...

AND as mentioned you want get that much space from the above cleanage !

in general:

I for myself would do an fresh and clean install.
at least if bugs turn up during running that old box and the need to debug them.

the question then is: 
what do I currently/really debug: F30 bugs or bugs somehow reaching down to F18
 
I would like to be on a save(r) side with a clean box, so 5 upgrades okay, but 
~12 ?

sure, it needs more work !
but all the work and hours you put in for the cleanage and stuff is more then 
~1h installation
plus some (depends on your setup) hours reinstalling additional packages and 
configuration.

thinks about it !
