Synaptics and software botique broken in ubuntu mate Release 22.04.1 LTS

[Neon John]

I just tried to install a package using synaptic package manager after the latest upgrade to Release 22.04.1 LTS (Jammy Jellyfish) 64-bit. It returns this error message:



E: The value 'impish' is invalid for APT:efault-Release as such a release is not available in the sources
E: _cache->open() failed, please report.




I've reinstalled the package using apt but no change.

Also Software Boutique does not load at all and I don't know the package name to apt.

Any help would be much appreciated.

Ubuntu 21.10 (Impish Indri) was the 35th release of Ubuntu, support ended on July 14, 2022.

take a look at your sources list files and remove the impish entry with your favorite text editor

cat -n /etc/apt/sources.list
tail -v -n +1 /etc/apt/sources.list.d/*

as to >>
"tried to install a package -- Software Boutique does not load at all and I don't know the package name to apt."

I can not hazard a guess as to what package you may be referring to

in small steps

we can do this

My release is Release 22.04.1 LTS (Jammy Jellyfish) 64-bit, current.

I removed everything in /etc/apt containing "impish". and verified with

jgd@den:/etc/apt$ sudo grep -R impish *

Which returned nothing. Yet synaptic is returning the same error.

E: The value 'impish' is invalid for APT::Default-Release as such a release is not available in the sources
E: _cache->open() failed, please report.

It must be looking somewhere else. I executed this:

jgd@den:/etc$ sudo grep -R -i impish *

which returned nothing except a word in the dictionary.

Where do I look next?

Re: software boutique, when I click on the menu item, nothing loads. What package do I need to install to make Software Boutique work again.
