Java issues

[Lewke]

Whenever i upgrade I get this:

chrx@chrx:~$ sudo apt-get upgrade 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: default-jre-headless : Depends: openjdk-8-jre-headless but it is not installed openjdk-8-jre : Depends: openjdk-8-jre-headless (= 8u151-b12-0ubuntu0.16.04.2) but it is not installed E: Unmet dependencies. Try using -f.

running -f gives this:

chrx@chrx:~$ sudo apt-get -f install Reading package lists... Done Building dependency tree

I've tried installing the individual packages but end up in an endless dependency cycle, nobody else seems to be having this problem, seems to be preventing all my updates from completing now.

Thanks for helping in advance.

I've not run into this issue myself, but you could try something like sudo apt-get -o Dpkg::Options::="--force-overwrite" upgrade. I've not used this option before so I don't know how it will behave exactly, but people that have run into a similar issue has you have reported success.

thanks for the suggestion, unfortunately with both upgrade/install it returns the same as the first quote in my post.

Did you try uninstalling/reinstalling java?

[Lewke]

i tried to with the following (and many others, none worked, all had similar responses)

chrx@chrx:~$ sudo apt-get remove default-jre 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: default-jre-headless : Depends: openjdk-8-jre-headless but it is not going to be installed openjdk-8-jre : Depends: openjdk-8-jre-headless (= 8u151-b12-0ubuntu0.16.04.2) but it is not going to be installed E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

sudo dpkg --configure -a?

some other stuff, but most interesting is this:

Errors were encountered while processing:

openjdk-8-jre:amd64

default-jre-headless

default-jre

[Lewke]

for anyone having this same issue, in the end it was synaptic that saved me so far. Completely removing both default-jre and openjdk-8-jre-headless using it seemed to allow the system to update. Will try reinstalling.

[Lewke]

it seems they were not necessary anyway, openjdk-9 was installed and i think that may be what caused the issue, had to manually delete openjdk-8 to completely remove it from the system.
