Any idea how to solve this problem?

Does it help if you change Mirrors in Software Sources?

[Pjotr]

What software sources do you have?

Code: Select all

inxi -r

[michalq]

Non-official software sources / PPA's galore....

Disable them all, test again, and when success: re-enable each disabled source one by one with testing in between. This should pinpoint the culprit.

Non-official software sources / PPA's galore....

As I said before:

Code: Select all

sudo apt update
sudo apt upgrade

works well without any problems, so PPA's galore is not a case ...

[Pjotr]

Try this:

Code: Select all

sudo apt-get install --reinstall synaptic mintupdate

[fmbonobo]

Same problem here.
Errors messages appears in the same way with or without ppa or additionnal repositories.
sudo apt update shows no errors in the console.

Update Manager>Edit>Sofware sources>Maintenace>Click first 3 in list - worth a try.

[davidpcoleman]

Mine was saying APT installation is corrupted. I tried several things. This worked for me and my updater is back to normal

Code: Select all

sudo apt update
sudo apt upgrade

Thanks to michalq for the idea. Worked great

[fmbonobo]

Code: Select all

sudo apt update
sudo apt upgrade

has no effect.
Same error messages.

[michalq]

Try this:

Code: Select all

sudo apt-get install --reinstall synaptic mintupdate

Does not help at all ...

[michalq]

Update Manager>Edit>Sofware sources>Maintenace>Click first 3 in list - worth a try.

Does not help, too ...

[fmbonobo]

This is what I get when Mintupdate is launched from the console

Code: Select all

doesn't help either

michalq,

Did you change Mirrors in Software Sources?

[fmbonobo]

Yes, but nothing changes
Same error messages with default mirrors or faster/closer mirrors

[sleeper12]

Try, one line at a time:

Code: Select all

apt reinstall mintupdate
mintupdate 

Or:

Code: Select all

apt reinstall mintsources
mintsources 

[fmbonobo]

Try both; same error

[sleeper12]

Did you try clicking 'Restore the default settings' in Software Sources?
