Post subject:  uberstudentsources && uberstudentupdate unmet dependencies

I have tried following the suggestion of the output, and to no avail I cannot upgrade several of the packages listed with:
sudo apt list --upgradable
even with the -f option for apt-get install.
I made use of the Software System Fixer without success; upon attempting an upgrade, the two uberstudent packages still have unmet dependencies and conflicts which I cannot seem to resolve on my own.

I'll look into this and post again shortly.

This make no sense if you are using the uberstudent.net repository with UberStudent 4.*. Those packages that are conflicting are part of a normal Ubuntu installation but are not part of the 4.* installation and are made to conflict for very good reason. They conflict with much more than just the base packages of uberstudentupdate and uberstudentsources:

Interestingly, after purging the conflicting packages I receive the same error. I checked the dependencies for uberstudentsources, and update-manager-core is listed as a forward dependency. With the conflicting packages purged, shouldn't the conflict be resolved when attempting an upgrade?
Thanks for your help Stephen, please let me know what information you may need from me to help resolve the conflicts and unmet dependencies.

ubuntu-manager-core is not a dependency but is declared under Replaces in the control file.

Let's try this. Open a terminal and run the following lines, one at a time:
mkdir "$HOME/Desktop/debs"
cd "$HOME/Desktop/debs"
wget http://uberstudent.net/pool/main/u/uberstudentupdate-rules/uberstudentupdate-rules_4.9.3.3_all.deb
wget http://uberstudent.net/pool/main/u/uberstudentupdate/uberstudentupdate_4.9.3.3_all.deb
wget http://uberstudent.net/pool/main/u/uberstudentsources/uberstudentsources_1.5.0.8_all.deb
wget http://uberstudent.net/pool/main/u/uberstudentsources-helper/uberstudentsources-helper_1.5.0.3_all.deb
sudo dpkg --force-all -i *.deb
rm -r "$HOME/Desktop/debs"
sudo apt-get update
Afterward, if there are no errors, attempt to update from the Update Manager

No errors were received following the suggested commands; when updating with the update manager, no available updates are found, nor are any errors encountered. To see if the original error persisted, I tried and sudo apt upgrade and the original unmet dependency & conflict still exists. I have used the purge command again, as recommended to determine if the packages have been reinstalled, and none of the previously purged packages are installed on the system.
Is it possible to determine which package is requesting the conflicting softwares when performing a package upgrade?
Running the following command gives me the attached list of available package upgrades.
clear && apt list --upgradable

Ah. I somehow missed that you're using apt-get upgrade and not just installing packages.

First, no matter what you might have learned before, apt-get upgrade is a HORRIBLE way to upgrade any Debian-based system. Expect destabilization.

Second, the Update Manager is correct. Your system is upgraded. Use the Update Manager. It's there for a reason. Expect stabilization.

I have no idea why apt list --upgradable does what you showed. Look carefully at the version numbers. None of those are new versions. Nothing is actually upgradable.

Ah, thank you. I can guess why apt upgrades would destabilise my system. I haven't experienced any system hangs or other issues, so I will cease using apt to upgrade my system manually; I'll stick with the Uberstudent Update Manager. I guess I wanted to feel like more of a power user than I really am! :ugeek: In the future I'll use the included software repositories to discover new software, unless it is unavailable; if unavailable, should I ask on the forums if there have been any stability tests done before I try installing software with apt or .deb packages?
