I upgraded a computer from Ubuntu Desktop 18.04 LTS to 20.04 and then 22.04. During the process I had an error related to snap not able to connect to the server or something, but I did not care since I don't need/use snap packages...

...except that the upgrade process also requires changing Firefox from a traditional apt version to a snap version. So now I have no Firefox at all. I tried following this to install the apt package but it didn't work, probably because of this error:

W: Failed to fetch https://ppa.launchpadcontent.net/mozillateam/ppa/ubuntu/dists/jammy/InRelease  Could not handshake: An unexpected TLS packet was received. [IP: 134.226.56.7 8080]
W: Some index files failed to download. They have been ignored, or old ones used instead.

Now if I try to install with apt I get this:

> sudo apt install firefox
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Package firefox 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 'firefox' has no installation candidate

If I try to install with snap:

> snap install firefox
error: cannot install "firefox": Post "https://api.snapcraft.io/v2/snaps/refresh": proxyconnect
       tcp: tls: first record does not look like a TLS handshake

I'm lost, how can I get Firefox back? (preferably the apt version)

Update: proxy

This machine is behind a proxy. The proxy is configured as indicated in this question for apt, but apt update still has an error:

  • @user535733 I'm not totally sure to be honest, but there was no similar error message asking me to abort or skip. all the regular apt packages have been successfully upgraded, so there was definitely access to the network. – Erwan Sep 06 '23 at 17:15
  • is a proxy set in your system? – nobody Sep 06 '23 at 17:23
  • @nobody indeed, I'm behind a proxy. Afaik it's configured properly but I could be wrong, I updated the question. – Erwan Sep 07 '23 at 17:02
  • For apt it seems correct set. Please try sudo apt-get -o Acquire::ForceIPv4=true update if possible. – nobody Sep 07 '23 at 17:19
  • @nobody I tried the command you suggested, no luck unfortunately. – Erwan Sep 07 '23 at 17:57
  • @nobody by any chance, can you think of some config issue which would cause connection to the mozilla repository to fail but works with ubuntu regular repositories? – Erwan Sep 07 '23 at 18:00
  • Nope sadly not. @Erwan – nobody Sep 07 '23 at 18:18

I didn't succeed setting up the Mozilla repository so I wasn't able to install the deb version of Firefox.

However I eventually was able to install the snap version, it turns out it this problem was due to my proxy indeed (thanks to @nobody and this answer):

sudo snap set system proxy.http="http://my-proxy"
sudo snap set system proxy.https="http://my-proxy"

Then snap was working:

snap install firefox
