Fix pkcon error cannot found file

Question

My disk is full and I found that PackageKit uses more than 12GB in cache folder. So I found that I can delete the cached files. I used the following command

[unix@localhost ~]$ sudo pkcon -c 8000000 refresh
Refreshing cache [=========================]
Loading cache [=========================]
Downloading repository information[=========================]
Finished [=========================]
Fatal error: Error when getting information for file “/var/cache/PackageKit/28/metadata
/phracek-PyCharm/repodata``/36899dd8cb609ee8604863268813e848e6d48b2448bad93a4037e14dcad30dcd-appstream.xml”: No such
file or directory

But I have this error about missing files and folders. Could some one help me to fix it?

Just out of curiosity: why are you running such an old version? Is it some hardware compatibility issues? — telometto, Sep 18 '22 at 19:21
@telometto I have installed a lot of softwares like Matlab and I dont trust to make a new setup. — xmaze, Sep 18 '22 at 20:42

Unless you absolutely need it, you can disable and mask PackageKit. I did some digging on Bugzilla and it seems to be an issue with < 28 of Fedora and PackageKit version < 1.1.19.

The "solution" (except upgrading the distro and/or package version), seems to be to be to disable & mask PackageKit:

sudo systemctl stop packagekit.service
sudo systemctl disable packagekit.service
sudo systemctl mask packagekit.service
sudo systemctl stop packagekit-offline-update.service
sudo systemctl disable packagekit-offline-update.service
sudo systemctl mask packgekit-offline-update.service

sudo rm -rf /var/cache/PackageKit   # optional

I don't know which version of systemd Fedora 28 uses, but if it is >= 220, you can pass the disable --now flag instead of stopping each service.

PS: If you want to use GNOME Software, you'll have to unmask and start the services again. But I don't think this should be a problem if you're comfortable updating your system using the CLI.
