Ubuntu GUI Injury
To be honest, the Ubuntu GUI looks really good, but there are also a lot of problems, and stability is really unpleasant. Recently, I have encountered a NetworManager management problem! I believe someone has met me! Ubuntu netwok-manager the system network services are not compatible with this version and the problem with the graphics card driver I encountered last time: I found some solutions on the Internet, such as link and link2, but you need to download various dependent packages. I don't want to download it, and his system is 12.04 different from mine. When I install other software, the dependency is resolved as follows: [plain] root @ aborn-lisp:/etc/apt # apt-get install squid Reading package lists... done Building dependency tree Reading state information... done You might want to run 'apt-get-f install' to correct these: The following packages have unmet dependencies: network-manager-dbg: Depends: network-manager (= 0.9.4.0-0ubuntu3) but 0.9.1.90-0ubuntu5. 2 is to be installed or libnm-util2 (= 0.9.4.0-0ubuntu3) but 0.9.1.90-0ubuntu5. 2 is to be installed or libnm-glib4 (= 0.9.4.0-0ubuntu3) but 0.9.1.90-0ubuntu5. 2 is to be installed or libnm-glib-vpn1 (= 0.9.4.0-0ubuntu3) but 0.9.1.90-0ubuntu5. 2 is to be installed squid: Depends: squid-common (> = 2.7.STABLE9-4ubuntu4) but it is not going to be installed E: Unmet dependencies. try 'apt-get-f install' with no packages (or specify a solution ). [plain] root @ aborn-lisp:/etc/apt # dpkg -- remove network-manager-dbg
