I do not have a problem with the keyring but with broken packages. I used Synaptic to fix broken packages and it gave the message that it fixed it, but I still have the errors:
1.- HP printing extras installation still gives the error:
2.- Skype does not install either:The following packages have unmet dependencies:
Printer-driver-hpijs: Depends: libhpmud0 (= 3.16.10 + repack0-1mx15 + 1) but 3.16.11 + repack0-1mx15 + 1 is going to be installed
E: Problems could not be corrected, you have retained broken packets.
Last week I got those packages installed fine with my MX-16 official installation in my Hard Disk. But since 3 days ago they fail in my SSD, the only difference is the problem with signatures and repos and that in SSD I installed the MX-16 with the KDE respin. I do not know what else to do, the complete messages are in this other post.Package skype: i386 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
Is only available from another source
E: Package 'skype: i386' has no installation candidate
Please note that I was able to install uGet without any problem in same MX-16 with the KDE respin.
Thank you for your help.
